The 3062 1kW Power Amplifier is an HF power amplifier delivering 1 kW PEP output across 1.6 to 30 MHz for continuous voice and data operation with Codan Envoy and Sentry-H transceivers.
1 kW PEP +/- 1 dB and 600 W average across the full 1.6 to 30 MHz HF range into 50 ohm impedance.
Rated for 100% continuous operation in all modes for voice or data, 100% normal speech over full temperature range.
Switched mode supplies vary RF transistor voltage with load and modulation to maximise efficiency and cut heat.
Spurious and harmonic emissions better than 60 dB below PEP; intermodulation distortion better than 32 dB below PEP.
Controls an external antenna tuner or coupler; the transceiver auto-tunes on low power before high power engages.
Safe under all loads; by-pass mode delivers 125 W PEP from the transceiver under excess VSWR, heat or fault.
19 inch 5RU rack mount with extensive heatsinks and thermostatically controlled dual speed front panel exhaust.
