50W Professional FM Broadcast Power Amplifier

Inc. Delivery to UNITED STATES

1 Watt Drive (can be more on request!)

All our amplifiers use a standard input of 1W. This means for 1W of drive power this amplifier will produce 50W of RF output 24/7 whilst maintaining international technical standards.

If you require a different input power level, no problem, we can do that easily. Just email or message us in the box below for more details.

Temperature Resilience

The first version of this unit was designed for use in the middle of East Africa, so we had to make it good, in fact not just good, amazingly good. We didn't disappoint our client, it was installed 5 years ago and is still fully operational, running day in and day out in the heat of Africa. If the ambient goes beyond 40C, the internal temperature protection starts to back off the RF power, gently, not any abrupt cut out, just a little to keep the internal temperature below 70C.

VSWR Resilience

Under severe load mismatch conditions (poor SWR, Return Loss) the unit automatically folds back the power to a safe level to protect itself, the antenna and cables from damage. When the load becomes again, full power restores automatically and instantly. The front panel has a forward and reflected power meter, so you can monitor the state of your antenna all the time.

High Stability

Our transmitters and amplifiers maintain their power and spectrum purity consistently, even if there is a VSWR mismatch, temperature fluctuation, or incorrect supply voltages. These devices are designed to perform reliably in challenging environments while still meeting the International Telecommunications Union (ITU) standards without fail.

Global Voltage Compatibility

All AC version of this product is truly globally compatible, you can plug it into any AC outlet in the world from 90 to 260V at 50 or 60Hz
