NOTES:
(1) /* = Denotes the type of power supply: AC, 48, or AC/48
(2) Gain specified at highest frequency.
(3) Distortions measured with 50-550 MHz analog CW (6 MHz spacing) and 550-1000 MHz noise at -6 dBc (average power per 6 MHz).
(4) Specified with 0 dB plug-in attenuators and 0 dB plug-in EQs.
(5) DC load current at +24 VDC per module.
(6) PP = Push-Pull; PD = Power-Doubled; GaAs = Gallium Arsenide; PDH = Power-Doubled High-Current
Operating temperature: 0°C to +50°C (+32°F to +122°F)
Humidity: 20-55% (without condensation)
