1GHz to 22GHz, 15W, GaN Power Amplifier

The ADPA1112 is a 1GHz to 22GHz wideband power amplifier with a saturated output power (POUT) of 42dBm, power added efficiency (PAE) of 25%, and a power gain of 14dB typical from 8GHz to 16GHz at input power (PIN) of 28.0dBm. The RF input and RF output are internally matched and AC-coupled. A drain bias voltage (VDD) of 28V is applied to the VDD1 and VDD2 pins, which have integrated bias inductors. The drain current is set by applying a negative voltage to the VGG1 pin. A temperature-compensated RF detector is integrated allowing monitoring of the RF output power.

The ADPA1112 is fabricated on a gallium nitride (GaN) process and is specified for operation from −40°C to +85°C.
