Product Detail

MAMF-011138
Integrated Dual Channel Switch and LNA Module 2 - 6 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
