RF Front-end Modules Enable Wireless Multimedia Services

( 1 Mar 2008 )

SiGe Semiconductor Inc. has launched two radio frequency (RF) front-end modules that will enable new wireless multimedia services in client access applications including game consoles, desktop and laptop computers. The SE 2547A and SE2548A are complete 802.11a/b/g/n WLAN RF front-end modules providing all the functionality required between the transceiver and the antenna in dual-band Wi-Fi systems. The devices each include the necessary power amplifiers, filtering, power detector, diversity switch, diplexers and associated matching circuitry in a fully tested module that measures just 25mm²—about one-third of the size of previous front-end modules on the market.

The high integration makes the new RF front-end modules ideal for portable and consumer applications including mini-cards for personal computing. The front-end modules can be used alone, or in stacked configurations to support multiple stream applications. The SE2548A is equipped with a single antenna port allowing it to be used in two-stream-by-two- antenna configuration. The SE2547A provides two antenna ports, allowing two-stream-by-three-antenna or two-stream-by-four-antenna configurations.
