This power amp is primarily designed for use with our 5W transmitter, however there is no reason why it cannot be used with any other 5W driver that will operate into 50 ohm termination. In an open environment the RF power increase from 5W to 30W will improve the range by about 2.5 times.
The whole power amp unit comes ready to use ' plug and play ' on delivery. Just hook the power amp to your antenna, transmitter drive and 13.8v (4.5 amp continuous) power supply and that's it, you're on..
Test equipment is not required to set up and operate this amp. The output stage delivers a minimum of 30W into a 50 ohm antenna/dummy load from 88 to 108MHz without ever having to take off the lid to carry out any tuning or tweaking.
High SWR conditions will not drive the amp unstable and furthermore the amplifier will not self oscillate without RF input drive or connection while the DC power is applied. Harmonics and spurious are below -50dB making the amp compatible with most countries licensing conditions.
The circuit design uses a very robust single stage discrete transistor, not an RF module. Our research shows that replacement output transistors, in the unlikely event they are needed, will be available for many years into the future.
Heatsink temperature on the amp is typ warm/hot and will operate 24 hours a day in most of worlds countries without an additional cooling fan.
