Introduction

The BGA622 is a wide band low noise amplifier, based on Silicon Germanium Technology B7HF. In order to provide the LNA in a small package the out-pin is simultaneously used for RF out and On/Off switch. This functionality can be accessed using a RF-Choke at the Out pin, where a DC level of 0 V or an open switches the device on and a DC level of VCC switches the device off. While the device is switched off, it provides an insertion loss of 24 dB together with a high IIP3 up to 20 dBm.
