RFICs enable 4G cellular base stations

Enabling high-density radio cards by combining multiple discrete functional blocks into a single device, the ADRF6601/2/2/4 series of mixers and ADRF6701/2/3/4 series of modulators meet the demanding performance required by higher-capacity base stations. With this breakthrough level of integration, the company claims that base station manufacturers can realize an unprecedented 60% reduction in board space and a significant savings on bill-of-materials costs.

The four ADRF670x products integrate a high-dynamic-range analog I/Q modulator, RF output switch, and PLL with integrated VCO. The modulator input bandwidth of 500 MHz can support either a specified band or complex IF up-conversion transmit signal paths.

The four ADRF660x products integrate a high-linearity active RF mixer, RF input balun for single-ended 50-Ω input, and a PLL synthesizer with integrated VCO. The active mixer provides a voltage conversion gain of 6 dB, alleviating the need for additional IF amplification over competing passive mixers. The differential IF output is capable of supporting IF frequencies up to 500 MHz.

Connector demand will be sluggish through the rest of the year

Connector book-to-bill ratio rises in August but expert says demand will slow

By Jim Carbone -- Purchasing, 9/30/2008 2:31:00 PM

Connector demand will be soft for the rest of the year because of low consumer confidence, high energy costs and turmoil in the financial markets which is slowing consumers spending. That’s the outlook provided by Ron Bishop, president of Bishop & Associates in St. Charles, Ill. in a recent report.

Bishop says the connector industry book-to-bill ratio increased to 0.99 in August from to 0.97 in July, which means for every $100 of orders that suppliers shipped, they received only $99 in new orders. August connector shipments were up 1% from August 2007 and 3.9% from July 2008. New connector orders were up 2.7% from August 2007 and 5.9% from July 2008.

But businesses are starting to be more cautious about spending and capital expenditures will probably slow, Bishop says. Still, the global connector industry will grow to 7.3% to $45.9 billion, according to Bishop.

Some connector prices will rise

By Gina Roos -- Purchasing, 8/14/2008

Continued increases in costs for metals and resins are impacting the connector industry and will result in price hikes for some interconnect products.

"Raw materials cost is the biggest issue," says Mike O'Connell, director of product management for Molex in Lisle, Ill. While the biggest materials price increases impacting connectors in the past year continue to be copper and gold, plastic resins are quickly catching up, O'Connell points out.

Molex recently announced 4–10% price increases for some products, effective July 1. The connector maker is also looking at additional price increases as customers' contracts expire. The company is also, in some cases, implementing copper or gold adders with OEM customers so as prices increase there will be a price change directly associated with it...

Shari Kolker, director of commodity management at EMS firm Celestica in Toronto expects to see price hikes of 5–40% for specialized connectors that have low demand and higher material cost content...

According to Kolker, standard commodity connectors are the least likely to be affected by commodity price increases because competition will keep prices in check. But unique connectors or highly customized products with a higher content of copper or gold are the most likely to see price increases.

Despite the rising materials costs, the connector supply base is still on track for growth.

The global connector industry is expected to grow 7.3%, reaching $45.9 billion in 2008, according to Bishop & Associates of St. Charles, Ill...

One notable trend in the connector industry is increased dual-source activity. Though it's nothing new in the industry, O'Connell believes it probably has been accelerated by the increase in materials costs to ensure dual suppliers to help combat raw material increases. For example, Molex and Amphenol TCS (ATCS) have signed a cross license/second-source licensing agreement that gives ATCS the right to manufacture and sell the I-Trac backplane connector system worldwide. In addition, Molex's recently developed high-speed, high-density Impact backplane connector system is now available from Tyco Electronics as a second source supplier...

Molex is now offering services to help OEMs design printed circuit boards (PCBs). By helping OEMs apply their connectors more cost efficiently, supplier help drive costs down on their entire application, O'Connell says. For example, with high-speed products, Molex is working with OEMs to reduce layer count, which significantly reduces the cost of boards. Molex is working on the weight and size of the power traces, which results in less copper on the board and thus lower cost.

Purchasers are involved so they understand the total cost of the application, and they should be involved to help drive the overall cost of the applied system, O'Connell adds.

Poort agrees there has been an increased focus on higher levels of service. FCI Electronics has responded with its Basics+ service program that includes readily available stock on standard products. In addition, to make it easier for buyers to find product information, the company has recently launched a number of micro web sites including one for power and mezzanine connectors that also includes its MezzSelect product selector guide.

Bishop: Connector prices will drop as demand weakens

Competition for orders should drive down prices

By Jim Carbone -- Purchasing, 7/16/2008 11:12:00 AM

Connector prices could fall in the second half despite higher raw materials costs because the strongest demand for connectors in 2008 may be over.

Connector orders were up for the first five months of the year, says Ron Bishop, president of researcher Bishop and Associates in St. Charles, Ill. “Year-to-date orders were up 13.9% through May. Sales are up 12.3% from one year ago.” But Bishop says there appears to be a slowdown in connector demand. In May orders were up only 4.2% from May 2007. In April, they were up 16.6%. He says double-digit monthly increases in orders in the second half are unlikely.

While sales were up 12.3% for the first five months of the year, revenue will rise 7% for the year, according to Bishop. If orders decline—indicating weaker demand—it will be hard for connector manufacturers to pass on higher costs for materials. Copper, gold and materials used in connector production have increased during the past 12 months.

Last year, when raw materials costs increased, “connector manufacturers started to increase prices to distributors and then slugged it out with large OEMs every time a new contract came up,” says Bishop. “Suppliers got some concessions.” The net effect was a 1-2% increase in prices. Usually connector prices fall 2-5% each year.

“In the second half, connector demand will be softer and it is going to be difficult for connector makers to not compete on price a little bit more aggressively to get the order,” says Bishop. “We are going to see some price erosion again.”

The High-Definition Multimedia Interface (HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART,component video, D-Terminal, and VGA. HDMI connects digital audio/video sources such as set-top boxes, Blu-ray Disc players, personal computers, video game consoles, and AV receivers to compatible digital audio devices, computer monitors, and digital televisions.

HDMI supports, on a single cable, any TV or PC video format including standard, enhanced, and high-definition video along with up to 8 channels of digital audio.^[1] It is independent of the various digital television standards such as ATSC and DVB as these are encapsulations of compressed MPEG video streams (which can be decoded and output as uncompressed video stream on HDMI).

HDMI products started shipping in autumn 2003 and currently over 800 CE and PC companies have adopted the HDMI specification (HDMI Adopters).^[2][3][4] HDMI began to appear on consumer HDTVcamcorders and digital still cameras in 2006.^{[5][6][7][8][9]} Shipments of HDMI are expected to exceed that of Digital Visual Interface (DVI) in 2008, driven primarily by the Consumer Electronics (CE) Market.^[10][11]
