Saw this NXP brand 1550 watt MRF1K50H-TF2 50V 27MHz "amplifier evaluation board" for sale for $1200. It can probably use the newest NXP 1800 watt 65V LDMOS as well. I've yet to find a schematic for it.
Was wondering since these are typically designed for use in thermal welders how wide is the bandwidth? Are these typically so narrow banded they are for use on only one 27 MHz frequency? Maybe just they way they are tuned when set up?
Can anyone get the 27MHz reference circuit info for this board?
