Products Modules SSPA 0.291-60

Aethercomm Model Number SSPA 0.291-60 is a high power UHF Airborne transmitter power amplifier. This model operates at 291 MHz with an AM or FM excitation. The typical output power is 100 Watts for FM operation and the power is typically backed off for AM operation. This RF module offers 50 dB of typical gain. The 2nd and 3rd harmonic levels are -80 dBc maximum. The internal RF components are gated on and off in less than 500 uSec maximum. Input and output VSWR is 1.5:1 maximum. This amplifier operates from a 28Vdc power supply with a typical current of 8.75 amps at 100 watts of output power. The amplifier is biased class AB so the current increases and decreases as a function of input drive. The size of this RF amplifier is approximately a width of 9.55" with a length of 4.96 inches and height of 4.86 inches.

Standard features include reverse polarity protection and over voltage protection with an output isolator for PA protection. The output is fully protected from an infinite VSWR at the RF output port. The input RF connector is TNC Female. The output RF connector is Type N female. DC and Command voltages are accessible via military circular connectors. This amplifier operates from -20C to +65C base plate. The RF enclosure has handles and other mechanical features. This RF product is pictured to demonstrate capability.
