The MAMF-011150 is a highly integrated compact surface mount module containing a PIN diode high power SPDT switch and 2-stage LNA with a 5 V power management chip in a 6 mm 40-lead HQFN plastic package.
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.
