The MAMF-011150 from MACOM is a High-Power Switch-LNA Front End Module that operates from 1.4 to 4.2 GHz. It has an integrated high-power PIN-diode SPDT switch, 2-stage low noise amplifier (LNA), DC converter, power management chip, and a PIN driver on a single integrated circuit (IC). The integrated LNA provides a gain of 37 dB with a noise figure of 1.1 dB and has an output P1dB of 19 dBm. This module can handle an input power of 80 W, provides an isolation of 50 dB, and has an insertion loss of 0.3 dB. It also includes a bypass switch on the second LNA stage. The module has a separate enable pin, which can be used independently or tied to the VCTRL pin on the board for simple Tx/Tx switching operations.
The MAMF-011150 requires a single DC supply of 5 V, a single 1.8/3.3 V-logic compatible Tx/Rx control signal, and consumes 108 mA of current. This RoHS-compliant switch-LNA module is available in a 40-lead QFN package that measures 6.00 x 6.00 mm and is ideal for high-power TDD 4G and 5G base stations, TDD-based communication systems, and wireless infrastructure applications.
