Microsemi AN1819 500W Amp Eval Board The FCC does not allow

The FCC does not allow the commercial sale of power amplifiers that operate below 30MHz with gain in excess of 15 dB

I and Q audio output that can directly modulate IQ baseband transceivers like the RS-HFIQ and the Softrock with low-latency CW

Current Hardrock-50 owners should consider upgrading the rear panel board in their amplifiers if:

Look for an upcoming 'hack' to add CIV output to deliver band change info to a QRO amplifier and the Hardrock-50 simultaneously

Microsemi AN1819 500W Amp Eval Board The FCC does not allowThis amplifier is a 500W or 700W design based on the Microsemi VRF2933 or VRF2944 MOSFET. We have an eval board that supports both devices. The board measures 10 X 15cm (4" X 6") and it is 1. 6mm (0. 063") thick with 2 oz copper and emersion gold plating for good heat dissipation and maximum conductivity. Run it with a pair of VRF2933's at 60V for 5W in, 500W output or use a pair of VRF2944's at 65V for 10W in, 700W output. More technical details can
