Designed, manufactured and assembled entirely the UK, the all new GEMINI 4 linear amplifier is a solid state linear amplifier with 300W output on both 50Mhz and 70MHz bands.

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.

With an RF section designed exclusively for us by Chris Bartram GW4DGU (of Mutek fame) Gemini uses the latest Freescale MRFE6VP6300HR3 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 design arcitecture of the RF section gives fully automatic 50MHz and 70MHz operation with no front panel band switching needed.

Furthermore GEMINI is a complete turnkey solution incorporating a complete 50V linear power supply so no external PSU is required.
