MOSFETS 2x IXFH52N50P2
 
CAN USE IT FOR CW/DIGITAL MODES ON 630M-160M BAND OR AM MODE ON MEDIUM WAVES FOR BROADCASTING*
 
BOARD SIZE WITH MOSFETS 115x135mm
 
 
*Note for cooling:
Must use two large heatsinks one for each mosfet so you can mount them directly with no isolation between the mosfets and heatsink only thermal paste.This way will have better heat transfer. But heatsinks must not touch each other and not touch the chassis/ground .So will need to isolate the heatsinks from the chassis box you will use.Also use of copper plates will have faster heat transfer to heatsinks.
