Microsemi AN1819 500W Amp Eval Board

Microsemi AN1819 500W Amp Eval BoardThis 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

Headers for direct connection to the RS-UV3 are suppied with the kit

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

2:1 up to 250 MHz

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

including heatsink

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