The Aethercomm model number SSPA 2.9-3.1-300 is a high power, pulsed or CW 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 and therefore can operate from 2.7 to 2.9 GHz or 2.7 to 3.5 GHz with similar performance.
This power amplifier is ideal for radar platforms as it is robust and offers high power and excellent power added efficiency while maintaining compliant pulse fidelity. It operates with a base plate temperature of –40° to +85°C. 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. Noise figure at room temperature is 10 dB typical, and the power flatness across the band is typically ±0.25 dB. Input and output VSWR is 2.0:1 typical.
This PA operates from a +50 V DC input voltage. The SSPA includes an external DC blanking command that enables and disables the module in 5.0 µsec typical. A logic low or open circuit disables the amplifier and logic high will enable the amplifier. Standard features include over/under voltage protection and reverse polarity protection. The output port 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.
