Tue, 09/04/2001 - 4:52am
Aethercomm P/N SSPA 7.1-7.3-10 is a High Power X Band SSPA used in the DSCC Exciter-Transmitter Subsystem. It is used as a TWT driver amplifier. It offers exceptional gain flatness across the band with very high gain. The internal DC-DC converter is extremely well regulated ensuring outstanding phase noise properties. This unit also has an internal PIN diode RF inhibit switch that allows a minimum of 40 dB of isolation when commanded on. Input/output VSWR is less than 1.5:1. Minimum P1dB is 37 dBm from -10°C to 70°C base plate temperature. Output power variation is less than 0.1 dB maximum across the frequency band. Output power stability is less than 0.1 dB at +60°C base plate. DC input power is 15.0 Vdc. Noise figure is less than 6.0 dB. Phase linearity is < 0.6° pk-pk at a 6 MHz offset. Linear group delay is < 2.0 nSecs at a 6 MHz offset. Output harmonics are -50 dBc maximum. Input/output open and short circuit protection is standard. Spurious emissions are < -60 dBc. Pulsed operation is standard with a RF rise time of < 500 nSec and RF fall time < 350 nSec.

This is an example of an Aethercomm standard product. Aethercomm designs and manufactures high performance, high power CW or pulsed SSPA's for commercial, military and satellite communications customers. Aethercomm is expert in the design, development and manufacturing of RF, microwave and millimeterwave amplifiers, transmitters, receivers and other communication systems components utilized by commercial wireless, military and satellite communications customers.
