Designed, manufactured and assembled entirely the UK, the all new GEMINI linear amplifier is a solid state linear amplifier with 300W output available in 6/4m 2m, 70cms and now 23cms versions.
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 NXP BLF6G13L-250P 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 1296MHz Gemini 23 also incorporates a front panel switchable 13.8v preamplifier supply on receive. This can be selected by the operator to be either an output voltage on the rear panel or a bias tee feed as required.

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