SPert1200 6m

The transistor amplifier "SPert1200 6m" is linear amplifier designed for work in amateur radio-communication systems, in 50 MHZ band or optionally 50 + 70 MHz, with all emitters. It is cooled with traditional aluminium radiator blowing with four 40×40,25mm fans.

About this amplifier

SPert1200 6m transistor amplifier is linear amplifier designed for work in amateur radio-communication systems, in 50 MHZ band or optionally 50 + 70 MHz, with all emitters. It is cooled with traditional aluminium radiator blowing with four 40x40,25mm fans.

They are made in a compact metal housing, containing such basic modules as:

  1. Power amplifier board on a single transistor LDMOS BLF188XR 1400W.
  2. Low pass filter board for 50 MHz and 70 MHz band (optional)
  3. Incident and reflected power measurement circuits with protection system against mismatch or missing antenna connection. An additional measuring circuit before the LPF filters prevents transistor damage due to possible filter damage.
  4. Ventilation system with PWM controller in four user-selectable modes:
  5. Microprocessor-based amplifier controller with display. 
  6. A 53.5V 56A switching power supply inside the amplifier.
