EB63A 140W HF Amplifier

Calculated at checkout

Product Description


The EB63 amplifier has an output of 140 watts (PEP) over a frequency range of 2-30MHz.  The amplifier uses two MRF454 transistors which are specified at 80 watts power output with 5 watts of input drive. The amplifier will accept Single Side Band (SSB) or Amplititude Modulation (AM) without external switching.  A carrier operated relaly circuit (COR) is on the same layout to make this an easy amplifier to add to any suitable radio with an RF output of 1-5 watts.
