... ALM-1612 GPS LNA-Filter Front-End Module Data Sheet Description Avago Technologies’ ALM-1612 is a GPS front-end module that combines a low-noise amplifier (LNA) with a GPS FBAR filter. The LNA uses Avago Technologies’ proprietary GaAs Enhancement-mode pHEMT process to achieve high gain with very low noise figure and high linearity. Noise figure distribution is very tightly controlled ...

... Note: The exceptional note figure performance of the ALM-1612 is due to its highly optimized design. In this regard, the Fmin of the ALM-1612 shown above is locked down by the internal input pre-match. This allows the use of relatively inexpensive chip inductors for external matching. 15 ALM-1612 Typical Noise Parameters 25° ...
