High Power Gallium Nitride (GaN) Amplifier: SSPA 1.70-1.85-20
Aethercomm Model Number SSPA 1.70-1.85-20 is a high power, Gallium Nitride (GaN) amplifier that operates from 1700 MHz to 1850 MHz minimum and is packaged in a rugged, compact enclosure. This amplifier is designed for operation in airborne environments and is used to boost the signals from telemetry transmitters. Minimum output power is 20 watts across the band at PSat. Small signal gain is 50.5 dB ± 0.5 dB across the band typically. Input and output VSWR is 2.0:1 maximum.
Standard features include reverse polarity protection, output short and open circuit protection, and over/under voltage protection. This RF module contains internal filtering to ameliorate the noise power at GPS L1 and L2 and also for harmonic suppression. This RF power amplifier operates from a 22 to 32 Vdc power supply. This unit operates from -40C to 85C base plate temperature. There is an over temperature shut off function to protect the unit when the temperature exceeds 90C base plate.
This high power RF module can be employed in high shock and vibration environments. Standard housing size is approximately 4.00(w) by 6.50(l) by 1.15(h) inches. For mounting and heat sink instructions, please contact the factory. An SMA female connector is standard on the RF input and output ports. DC and logic connections are accessible via a DSUB connector.
