Now available from RF and microwave component specialist Link Microtek is a range of microwave amplifiers that are competitively priced but are said to provide the quality and performance required for space, military and commercial communications applications.

SiGe Semiconductor has announced the SE2559L, an RF front-end module designed to improve integration and reduce cost of Wi-Fi systems compliant to the 802.11b/g specification. The new RF front-end is based on a highly integrated architecture that is about 60 percent smaller than competitive products. With high feature integration, the SE2559L eliminates several external components, allowing manufacturers to reduce the bill of materials cost for 802.11b/g functionality by about 15 percent. The small size and low cost makes the SE2559L ideal for access points, laptops, PC cards and embedded Wi-Fi applications.

Texas Instruments has announced the TLK2711HFGQMLV 1.6 to 2.7 Gigabits per Second Serializer/Deserializer. A member of the WizardLink family of multigigabit transceivers, the device is qualified to MIL-PRF-38535 (QML) Class V and is designed to support serial interface in high speed data bus applications for aerospace equipment, such as satellites.

STMicroelectronics has announced that it is sampling a new digital AM/FM radio receiver chipset for use in automotive applications. Sophisticated digital signal processing techniques allow the chipset to feature excellent reception quality while reducing interference even in presence of challenging signal conditions such as weak field and strong multipath (reflection from mountains and buildings).

Silicon Laboratories has announced the Si4901 AeroFONE single-chip phone, the industry’s most integrated, highest performing single-chip phone for the GSM ultra low cost handset (ULCH) market. The Si4901 expands the company’s family of single-chip phones to address demand for low cost, highly integrated GSM handsets in emerging economies.

Melexis has entered the market for accurate GPS position sensing with its angular rate sensor or gyroscope. The MLX90609-N2 will enhance the accuracy of GPS instruments in situations where satellite reception is lost, for example in tunnels, between tall buildings and mountainous terrain.

Texas Instruments has introduced the TPA5050 digital audio delay with IIC control. Designed for high definition and flat panel TV applications, the TPA5050 digital audio delay provides cost-effective synchronization of audio and video in a single integrated package that conserves board space and simplifies channel configuration.

Silicon Laboratories has announced what is said to be the industry’s most highly integrated, IEEE 802.3af compliant, Power over Ethernet controller for powered device applications. The Si3400 is the only PD controller to integrate on-chip diode bridges, a transient surge suppressor and a switching regulator field effect transistor. The Si3400 controller’s unprecedented level of integration simplifies PoE design efforts by reducing the total bill of materials, printed circuit board area and time to market.

The latest Litelink and Cybergate devices from Solid State Supplies provide interfaces for connection to telephone networks for both voice and data applications combining all of the required functionality and compatibility.

Alpha Micro Components has available Teridian Semiconductor's new MicroPHY transceiver for embedded 10/100 Ethernet applications. Packaged in an ultra small 5mm x 5mm QFN package, the Teridian MicroPHY is said to be the World's smallest Fast Ethernet PHY. Targeted at consumer audio-video and industrial products the 78Q2123 features Hewlett Packard's "Auto-MDIX" technology whilst also providing a full 802.3 Media Independent Interface.
