Description
M/A-COM’s CDMA 900 Filter/LNA is ideally suited for all
Basestation applications. The filter performance allows for 97dB
rejection at 898 MHz, while the balanced LNA possesses
excellent intermodulation performance, low noise figure and
controllable gain.
Custom models can be designed to fit other electrical and
mechanical requirements.
