New GaN MMIC Power Amplifier Delivers 10W from 10 MHz to 10 GHz
Hittite Microwave Corporation has introduced a new GaN HEMT MMIC Wideband Power Amplifier which is ideal for test & measurement equipment and military EW and ECM applications up to 10 GHz.
The When biased for maximum output power, the HMC999 consumes 1100 mA of quiescent current from a +48V supply, and achieves approximately 18% power added efficiency at saturation. This compact MMIC power amplifier delivers 10 Watts of saturated output power in a chip area of only 7 mm2, equating to a power density of 1.5 W/mm2 across 3 decades of bandwidth. The HMC999 is extremely robust and is designed to reliably operate into partially reflective loads and to tolerate very high incident power levels.
The HMC999 is matched to 50 Ohms on-chip, and requires several external bias decoupling capacitors and an external bias tee for drain bias injection. Samples are available from stock and can be ordered via the company's e-commerce site or via direct purchase order.
