Product Description
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.
