Avago Technologies’ new ALM-2712 is a front-end module for mobile GPS applications which integrates pre- and post-high rejection FBAR filters. This integrated FBAR filter provides low insertion loss in GPS band frequencies and excellent out-of-band rejection at cellular, DCS/PCS and WLAN band frequencies, making it suitable for use in simultaneous GPS (S-GPS), voice and data operations.
By integrating the low noise amplifier (LNA), FBAR filters and other RF matching components into the module, the ALM-2712 does not require any external RF matching components. It also has a built-in shunt inductor at the RF input pin to enhance ESD production, which allows the device to survive more than 3 kV of human body model (HBM) ESD charge at the RF input pin.
The ALM-2712 is housed in a 3 x 2,5 x 1 mm MCOB package and is suited for use in space constrained applications. At a typical operating condition of 2,7 V and 7,5 mA, the module delivers a 1,26 dB noise figure, 14,2 dB gain, and +5 dBm input third order intercept point (IIP3) and 89 dBc/80dBc/72dBc of out-of-band rejection at cellular, DCS/PCS and WLAN band frequencies.
