2 to 6 GHz GaN Power Amplifier
11
0

The ADPA1113 internally matched GaN power amplifier operates from 2 to 6 GHz and delivers an output power of 40 W (46 dBm) with small-signal gain of 40.5 dB and a power-added efficiency (PAE) of 39%. It is well suited for CW applications such as EW systems, test and measurement equipment, and radars. It does not require external matching or AC coupling to achieve full-band operation and integrates a drain bias inductor, so no external inductor is required for amplifier bias. Return loss at the input is 18 dB and 7 dB at the output, with a withstand threshold of 500 VDC. The amplifier requires a DC supply of 28 V and a quiescent current of 750 mA. It is housed in a 14-lead LDCC package and measures 9.8 x 8.2 mm.
