LNA + T/R Switch
Tuning Range: 2.4 to 6.0 GHz

The GRF2581 front-end-module combines a high performance, low noise amplifier along with a high linearity, T/R switch for WLAN/ISM and other applications up to 6.0 GHz. The device exhibits outstanding noise figure (NF) of 1.6 dB along with a high gain of approximately 15.5 dB at 5.5 GHz.

The device is operated from a single positive supply of 2.7 to 5.0 V and uses an ultra-small 1.5 mm DFN-6 package.

Consult with the GRF applications engineering team for custom tuning/evaluation board data and device s-parameters.
