300W amp 10W in 1.8-54 MHz SDR Hermes ANAN, FLEX-1500 CWithSSB without VRF2933
300 W output HF / 50 MHz amplifier SSB/CW for SDR ANAN-10, FLEX-1500 etc. Without transistors 2xVTF2933 This device is designed for use with SDR radios , like ANAN-10, FLEX-1500 or others.
With 6 to 8 W input power from SDR it delivers 300W output to your antenna. The amplifier's output is filtered by LPF with diplexer, so the second and higher harmonics of transmitted signal are suppressed for more than -47 dBc. To switch the filters you need simple open-collector circuit in SDR or external mechanical switch. This amplifier may be used with QRP transceivers like FT-817 or IC-703 (with automatic band decoder) also.
You must set matched pair of VRF2933 MOSFET transistors (see schematic) in AB-class. 2-tone measured IMD 3 is -40 dBc. New version has transmission line type output transformer for better perfomance. Measured by KC901H network analyser suppression of second and third harmonics (amplifier with diplexer) is: 10 meters 2nd -52 dB 3rd -55 dB 20 meters 2nd -54 dB 3rd -47 dB 80 meters 2nd -53 dB 3rd -51 dB. The power supply requirements is 50V 10 - 12A.
Through user programmable pins of accessory connector. Board size 190 x 165 mm. This device does not include heatsink.
