The performance of the amplifier was evaluated in standard laboratory ambient temperature conditions. The baseplate temperature was allowed to deviate to assess performance with respect to temperature. Figure 6 summarizes this power, frequency and bandwidth performance. The amplifier was also subjected to a random vibration in three axes to verify spacecraft launch survivability. During vibration, telemetry was monitored to verify bias line continuity. The data acquired gave no indication of interrupted bias current and thus verified the design integrity from a DC perspective. After completion of the vibration test, the amplifier was evaluated in terms of the RF performance. A frequency shift of 120 MHz was noted, however, the power and bandwidth performance was unchanged. The change in frequency was traced to movement in the dielectric sleeve which surrounds the bias line in the driver stage. This sleeve was returned to its proper position, and nominal performance was again observed.
