Power Gain (V s1 = V s2 = V s3 = V s4 = V s5 = 7.5 V; V cont = 3.75 V)
Control Voltage (P in = 0 dBm, P out = 4.0 W, V s1 = V s2 = V s3 = V s4 = V s5 = 7.5 V,
Adjust V cont for specified P out )
Efficiency (Same condition as for V cont )
Current Drain (Same conditions as for V cont )
Input VSWR (Same conditions as for V cont )
Harmonic Content (Same conditions as for V cont )
Leakage Current — I s2 + I s3 + I s5 (V s2 = V s3 = V s5 = 7.5 V; V s1 = V s4 = 0 V
V cont = 0 V; P in = 0 mW)
Standby Current — I s1 + I s4 (V s1 = V s2 = V s3 = V s4 = V s5 = 7.5 V
V cont = 4.0 V; P in = 0 mW)
Load Mismatch Stress (V s1 = V s2 = V s3 = V s4 = V s5 = 9.0 V;
P in = 2.0 mW; P out = 6.0 W; Load VSWR = 20:1, All Phase Angles.
Adjust V cont for Specified P out )
Stability (V s1 = V s2 = V s3 = V s4 = V s5 = 6.0 to 9.0 V; P IN = – 1.0 dBm to + 3.0 dBm;
P out = 1.0 W to 4.0 W; Load VSWR = 6:1, All Phase Angles;
Adjust V cont for Specified P out )
