Gallium Nitride Broadband RF Power Amplifier: SSPA 0.020-0.520-125

This amplifier operates with a base plate temperature of 85C with no degradation in the MTBF for the GaN devices inside. It is packaged in a modular housing that is approximately 3.4" (width) by 6.4" (long) by 1.0" (height). This amplifier has a typical P3dB of 100-125 watts at room temperature. Noise figure at room temperature is 10.0 dB typical. This amplifier offers a typical gain of 58 dB with a typical gain flatness of ± 2.0 dB. The power and gain flatness across the band is extremely flat for the bandwidth. Input VSWR is 2.0:1 maximum. Class AB quiescent current is ~2.0 amps typical employing a 28 Vdc supply. This PA operates from a 28 Vdc input voltage.

This SSPA includes an external DC blanking command that enables and disables the module in 12 to 15 uSec typical. Faster switching times are easily achievable. Standard features include over/under voltage protection and reverse polarity protection. The output is fully protected from an open or short circuit presented to this port with no damage. Input/output RF connectors are SMA female. Other connector types can be configured for airborne applications. DC and command voltages are accessible via DC feed through capacitors.

Features:

• Operation from 20 MHz to 520 MHz min
• Small Signal Gain 58 dB typical
• 50 % Typical Power Added Efficiency
