Designed, manufactured and assembled entirely the UK, the GEMINI 4 linear amplifier is a solid state DUAL BAND linear amplifier with 300W output on 70MHz and approx 270W on 50Mhz
The amplifier can now also be specified with a rear panel 0dBm SMA socket for predistortion linearisation for use with the latest generation of SDR’s.
Designed to fill a market gap between the low power outputs of transverters and smaller rigs and the 1kW plus amplifiers that not all users want or can afford the Gemini range combines low drive requirements with instant on solid state performance in a compact stylish package.
The Gemini RF section uses the Freescale MRFE6VP6300H LDMOS device for high performance and maximum ruggedness. This, combined with built in protection for overdrive, high SWR and over temperature ensures solid reliable performance at high outputs for long periods. The unique RF design architecture has resulted in fully automatic DUAL BAND capability giving both 50-54MHz and 69-72MHz coverage without any external bandswitching.
Furthermore GEMINI is a complete turnkey solution incorporating a complete 50V linear power supply so no external PSU is required.
