Description

This QRP tuner provides wide range matching of loads from 12.5-400 Ohms (& beyond) over a frequency range of 1.8-55MHz at powers of up to at least 100W. The unique design incorporates all components onto a single PCB with no air wired cores or coils.  It uses a series of fixed RF inductors with self resonant frequencies well past the operating range and real air-variable capacitors instead of cheap, lossy polyvaricon capacitors.  This tuner has been designed for hobbyists interested in integrating a tuner into their HF transmitter or transceiver kits or portable / emcomm kits.

Other features include:

  • Compact size – 145mm x 65mm (PCB) with corner mounting holes
  • BNC, SMA or direct wired input/outputs
  • Tuner bypass switch
  • Switch selected Internal 50 Ohm 20W load
  • Pi Network tuner configuration for wide range tuning into loads less than or greater than 50 Ohms
  • 12 position inductor switch with all inductors capable of 2.5A RMS RF
  • 2 380pF Air variable capacitors with 500V max voltage rating
  • Can be purchased as a kit or assembled. Some surface mount soldering required.
  • Note: Knobs not included
