A 125W Pulsed Ku-Band Power Amplifier From Sophia Wireless

The MPC8-1520 solid-state power amplifier provides an unparalleled size, weight and power combination. The SSPA features 125 W of power, 250 ns DC switching, 47000 mF capacitive DC storage, 45 dB gain with temperature compensation, forward and reverse power monitor with RS422 readout and a monitor and control processor, including bias sequencing control. The features and options are ideal for advanced Ku-band radar systems in military airborne platforms such as terrain-following and multi-mode radar systems, as well as navigation systems. The amplifier size is 11.1" ´ 4.5" ´ 3.1" and its weight is less than 5.1 lbs in its indoor configuration.

The MPC8-1520 solid-state power amplifier provides advanced radar systems with 125 W of RF power while the RF output power noise level during off periods is -172 dBm/Hz. The 250 ns DC switch (TTL controlled with a coaxial trigger) and the internal 47000 mF capacitor bank reduces the thermal management requirements and enables excellent power efficiency. A temperature compensation circuit minimizes gain and power variations.
A forward and reverse power monitor simplifies the system power settings and reverse power protection. The safety controls include thermal and bias protection sensors to ensure reliable performance from initial system integration to harsh field environments.
