4 HF Linear Amplifier Pallet 1200 Watt P.E.P together with 1 Combiner 2Kw P.E.P:


4 (FOUR) HF Linear Power Amplifier Pallet 300 Watt P.E.P (4X300=1200Watt)Designed for HF - VHF Broadcast and Ham radio Bands this LinearAmplifier incorporates transmission line transformers technologyand MOS-FET device to enhance ruggedness and reliability.PHV303 is an RF Power Amplifier designed for the HF Broadcast or Ham RadioBands transmitters or power amplifiers.PHV303's output power is 300 Watt P.E.P. minimum at 50 Ohm load in the rangeof 1.5 - 30.0 MHz and 250 Watt P.E.P. in the range of 30.0 - 54.0 MHz.This PA amplifies the input RF signal typically by 18dB, note that there is on boarda 3db attenuator that can be removed in order to increased the gain by 3dbit operates at 50V / 13A max. The operating class is AB and the quiet current is1.0A. The Amplifier consists of one Push-Pull amplifying stage with activecomponent a MOSFET BLF278 or MRF151G or equivalent. 1.5 - 54.0 MHz -Input / Output : 50 Ohm -Push - Pull Class AB -Efficiency : 55% typical -Devices: BLF278 or equivalent 1 (ONE)Combiner unit.-----4 Way HF - VHF Power Splitter - CombinerDesigned for combining four RF Power Amplifiers in theHF 1.5 - 54 MHz Frequency range.o 50 Ohm plortso Pout : 2KW P.E.P.
