ALM-2712 GPS Filter-LNA-Filter Front-End Module Data Sheet Description Features Very Low Noise Figure: 1.26 dB typ. Avago Technologies ALM-2712 is an ultra low-noise GPS front-end module that combines a low-noise amplifi er Exceptional Cell/DCS/PCS/WLAN-Band rejection (LNA) with GPS FBAR fi lters. The LNA uses Avago Tech- Advanced GaAs E-pHEMT & FBAR Technology nologies proprietary GaAs Enhancement-mode pHEMT Low external component count. process to achieve high gain with very low noise fi gure CMOS compatible shutdown pin (SD) and high linearity. Noise fi gure distribution is very tightly ESD: > 3kV at RFin pin controlled. A CMOS-compatible shutdown pin is included Adjustable bias current via single external resistor/ either for turning the LNA on/off , or for current adjust- voltage ment. The integrated fi lter utilizes an Avago Technologies leading-edge FBAR fi lter for exceptional rejection at Useable down to 1.8V supply voltage Cellular, DCS, PCS and WLAN band frequencies.
