Aethercomm Part Number SSPA 1.35-1.45-80 is a high power, pulsed solid-state amplifier used for military telemetry and data transmission. This SSPA supports pulse widths up to 100 mSec with duty cycles from 0.1% to CW operation. Minimum output power is 80 watts at 85°C base plate. The unit will operate from -50°C to 95°C base plate. Gain at saturated output power is < 40 dB across the band. Small signal gain is 45 dB ± 2 dB with a gain flatness of ± 0.5 dB. Pulse droop across a 4 mSec pulse is 0.2 dB. Rise and fall times are less than 1000 nSec. Input VSWR is 1.5:1 max. Harmonic levels are < 30 dBc at maximum saturated output power. Peak current is 13 amps maximum.

This PA operates from a 28 V DC supply with a quiescent current of 1 amp. All the active devices contain a fully temperature compensated active bias circuit which keeps the quiescent current within 10% of its nominal value from -50°C to 95°C. Standard package size is 30 × 70 × 10. Six mounting holes are located on the bottom of the housing. Input/output RF connectors are SMA female standard.
