The all new Gemini 70-1K is a solid state 1000W CW output Linear Amplifier for 430-440Mhz.

From the same stable as the Gemini 2-1.2K the Gemini 70-1K has been designed from the start with high duty cycle usage in mind. The core of the amplifier is dominated by a 7.5Kg aluminium heatsink cooled by three temperature controlled fans making it ideal for dedicated EME / MS / FSK / JT mode users and contesters.

The Integral Power Supply units will accept 100-260V Mains Input so the unit can be used worldwide without any modifications.

Specifications are:

  • Max output 1000W 430-440MHz
  • P1dB 800W output
  • Spurious outputs <55dB wrt 1000W
  • Input R/L >15dB
  • Drive levels 20W
  • Built in sequencer and Bias T feed for masthead preamplifiers
  • Protection for Overdrive/SWR/Over Temperature
  • RX Insertion Loss <0.3dB
  • Overall efficiency at 1kW output >60%
  • RF output meter
  • RF Device 1 x BLF188XR LDMOS **
  • Power requirements 100-260V 50-60Hz
  • Dimensions 315mm wide x 180mm high x 360mm deep
  • Weight 14,5Kg
  • Made in the UK.

The Gemini 70-1K is quiet in operation. Main cooling fans only run when they need to and are controlled by our own PIC fan controller giving stepless speed control proportional to temperature.
