SW 400 Watt PWM with DDS class D AM transmitter pallet.Freq.range 3.5Mhz-7.5Mhz

Description

AM DDS class D transmitter pallet module.
What you get from this sale is a complete board assemled and fully tested.The unit is capable to produce a carrier of
400w and when modulated you can expect 1600w(pep) maximum when supplied with 85vdc.
With less input voltage you will get less output power.With 65 voltDC you will get 200watt,with 75voltDC 300watt and with
85voltDC you will get 400watt.Max voltage 95voltDC you get 500 watt.
