High-gain PA for 4G

8 February 2012 Telecoms, Datacoms, Wireless, IoT

Avago’s MGA-43128 is a new high-gain, high-linearity power amplifier (PA) for high-data-rate applications found in 700-800 MHz cellular infrastructure equipment. The device combines high signal transmission quality with low power consumption for LTE AP, CPE and picocell equipment, and can also serve as a base station driver amplifier. RF input is fully matched while the output includes integrated pre-match circuitry for matching and application simplicity. An integrated bypass switch controlled attenuator provides up to 18,0 dB attenuation, and the device also has a temperature-compensated power detector on-chip. The MGA-43128’s linear output power allows single 5 V supply operation and useable performance down to 3,3 V.
