Products Modules SSPA 2.9-3.1-300

Model Number SSPA 2.9-3.1-300 is a high power, pulsed or CW Gallium Nitride (GaN) RF amplifier that can be employed in Radar or other applications throughout the S Band Frequency range. This amplifier is optimized for operation from 2.9 to 3.1 GHz. The devices in the amplifier are not matched therefore; we can operate from 2.7 to 2.9 GHz or 2.7 to 3.5 GHz with similar performance. Please contact the factory with any questions. This PA is ideal for radar platforms as it is robust and offers high power and excellent power added efficiency while maintaining compliant pulse fidelity. This amplifier operates with a base plate temperature of -40C to +85C. It is packaged in a modular housing that is approximately 5.00” (width) by 8.00” (long) by 1.94” (height). The weight of this unit is 2.5 pounds typical. This amplifier has a typical peak output power of 300 to 400 watts at room temperature (review the data on page 2 for frequency vs power across the band). Noise figure at room temperature is 10 dB typical. The power flatness across the band is typically ± 0.25dB. Input and output VSWR is 2.0:1 typical. This CW Gallium Nitride RF Amplifier operates from a +50 Vdc input voltage.

This SSPA power amplifier includes an external DC blanking command that enables and disables the module in 5.0 uSec typical. A logic low or open circuit disables the amplifier. Logic high will enable the amplifier. 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. DC and command voltages are accessible via a DSUB connector. Contact the factory with any questions you may have.
