Modules Enable Wireless Multimedia Services
SiGe Semiconductor, Inc. announces its models SE2547A and SE2548A radio frequency (RF) front-end modules that enable wireless multimedia services in client access applications including game consoles, desktop and laptop computers, and home access points. They are complete 802.11a/b/g/n WLAN RF front-end modules that provide 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 25 mm2. The high integration makes these modules suitable for portable and consumer applications, including mini-cards for personal computing. These front-end modules can be used alone or in stacked configurations to support multiple stream applications.
