Product Detail

Integrated Dual Channel Switch and LNA Module 2.3 - 4.2 GHz

The highly integrated Dual Channel Switch and LNA Module includes two Antenna Switches and two 2-stage low noise amplifiers in a compact low cost 6 mm QFN package. The second stage LNAs can be bypassed. Mixed technologies are used to achieve high power handling, low noise figure, and low power consumption. The module only needs a single +5 V supply. T/R switch, LNA enable, and bypass function can be controlled with 1.8 V or 3.3 V logic.
