New section which Integrates an FBAR Pre-Filter with the Low Noise Amplifier
New GPS Front-End Module Targets Designers of Low-Power Handset as well as Personal Navigation Device Applications
Avago Technologies (Nasdaq:AVGO), the heading retailer of analog interface components for communications, industrial as well as consumer applications, currently introduced the industry’s initial rarely integrated tiny GPS front-end modules which mix the movie bulk acoustic resonator (FBAR) filter with the high-gain, low sound amplifier (LNA) which offers higher opening levels. Avago’s ALM-1912 integrates the LNA as well as the high-rejection pre-filter in the tiny compress package to yield the finish as well as compress high-performance GPS air wave magnitude (RF) front-end procedure which can assistance to facilitate the pattern of the far-reaching operation of GPS handset applications.
Avago’s ALM-1912 is written for make make use of of in mobile handsets, personal navigation inclination (PND) as well as alternative GPS-enabled applications. This GPS front-end procedure is housed in the tiny 2.9 by 2.0 by 1.0 mm MCOB package to minimize the volume of printed circuit house space compulsory as well as is preferred for make make use of of in space compelled applications. The formation of FBAR pre-filtering in the ALM-1912 enables the procedure to yield well-developed rejecting during Cell, PCS, as well as WiFi/Bluetooth frequencies. Additionally, this GPS front-end procedure effectively leverages Avago’s 0.25 µm GaAs enhancement-mode pHEMT routine to broach the 1.62 dB sound figure, 19.3 dB gain, as well as +1.5 dBm submit third sequence prevent indicate (IIP3) as well as some-more than 50 dBc of out of rope rejecting during standard handling conditions of 2.7V as well as 6 mA.
Simultaneous GPS (S-GPS) as well as alternative location-based GPS services need the tall turn of receiver sensitivity. Avago’s ALM-1912 delivers the really low sound figure as well as tall linearity which helps to significantly urge the attraction of GPS handset applications. A CMOS-compatible shutdown pin is enclosed for branch the LNA on/off or for stream adjustment. The integrated pre-filter utilizes Avago’s leading-edge exclusive FBAR filtering technologies to yield well-developed rejecting during Cell/PCS-band, as well as WiFi/Bluetooth frequencies creation it an preferred resolution to assistance raise the opening of GPS receivers for S-GPS operation in handsets as well as alternative mobile devices.
The ALM-1912 has the built-in shunt inductor during the RF submit pin to raise ESD production, which allows the device to tarry some-more than 3kV of Human Body Model (HBM) ESD assign during the RF submit pin. By integrating the GPS LNA with pre- as well as post high-rejection FBAR filters, the high-performance ALM-1912 simplifies as well as shortens the RF pattern process, reduces member count, as well as provides glorious RF opening levels which have been vicious in GPS applications.
