RFHA1025

280W GaN Wideband Pulsed Power Amplifier

The RFHA1025 is a 50V 280W high power discrete amplifier designed for L-band

pulsed radar, air traffic control and surveillance and general purpose broadband

amplifier applications. Using an advanced high power density gallium nitride (GaN)

semiconductor process, these high performance amplifiers achieve high output

power, high efficiency and flat gain over a broad frequency range in a single pack-

age. The RFHA1025 is a matched power transistor packaged in a hermetic, flanged

ceramic package. The package provides excellent thermal stability through the use

of advanced heat sink and power dissipation technologies. Ease of integration is

accomplished through the incorporation of single, optimized matching networks

that provide wideband gain and power performance in a single amplifier.
