THE new Ophir model 4012 class A/AB solid-state power amplifier with 250 watt saturated power output, available from Westek Electronics , is designed for UHF satellite communications in the frequency range of 290 to 320MHz.
The Ophir 4012 has excellent harmonic performance having harmonics contributions of less then -20dBc at a power output of 200 watts.
Small signal gain exceeds +54dB and small signal response flatness is ±0.75dB max. Spurious signal contribution is less than -60dBc at a power output of 200 watt. Input signals can be CW, AM, FM, PM, and pulse
The Ophir 4012 is available in various options: rack-mounting (100-240V ac) with rear panel connectors, front panel connectors, or the former two with control panel or with Ethernet interface.
Other interface options are IEEE488 and RS232. The amplifier is suitable for operation in ambient temperatures from 0°C to +50°C, up to 95% RH, and to altitudes of 3000 metres.
