The device features high power handling, high
isolation at Tx mode, and high gain, low noise figure
RX mode. It has an integrated bias controller
utilizing a boost circuit. The switch portion requires
only a single 5 V supply, and a single TX / RX
control signal that is 1.8/3.3 V logic compatible.

The 2-stage LNA has an additional bypass feature
for the second stage and has a separate Enable pin
which can be used independently or tied to the
VCTRL pin on the board for simple TX/RX switching.
