2 Meter (144 to 148MHz) 1000 Watt LDMOS RF Amplifier Board
This 2 Meter RF Amplifier Board includes 1 BLF188XR LDMOS Transistor and a Copper Heat Spreader (drilling and tapping is required). The transistor used is extremely rugged and can withstand an SWR mismatch for 65:1 or greater at all phase angles. The PC board is professionally fabricated and is designed to produce a very high efficiency (greater then 85%). The amplifier is design for the 2 Meter VHF Band (144 to 148MHz) and supports AM, FM, CW, and SSB operating modes. The bias current is preset to 500mA and can be readjusted by use of an independent potentiometer. The board dimensions are 4" wide by 7.5" long. A large aluminum heat sink and forced air are required for proper cooling and for reliable operation. Units ships with schematic, installation guidelines, and operating setup instructions. I also provide free technical support by email or phone call.
