The EME171B Universal Microwave PC board was designed as a low cost way of experimenting on the microwave bands, and allows various building blocks like Transverters, multipliers, are RF amplifier to be constructed.

A complete Transverter for 5800MHz can be easily constructed using a number of Kits and components available from Mini-Kits. The picture below shows a prototype chassis with a fully working transverter for 3400MHz. Pipe cap cavity filters are used to effectively filter out image and local oscillator frequencies, allowing IF frequencies down to 144MHz to be used.


The use of Cavity filters using pipe-caps have been used by Hams for many years, and make excellent filters that can be easily adjusted in frequency and bandwidth. They also allow relatively narrow filters to be constructed which more effectively filter harmonics and oscillator noise, allowing low Transverter I/F frequencies to be used. Cavity filters also improve the stability of the design making it easier to mount into a smaller enclosure, compared to printed strip line filters that can radiate RF.

Most of the EME5800 series Kits require +9 volts, so that they can easily be used for portable battery operation. Only the EME5800-TX Driver Kit has the requirement of +12 volts for it's high 1dB compression Gali-84 amplifier, to produce a clean signal from the transmitter.

The EME5800 series Kits use modern low noise high gain amplifiers, including the Mini-Circuits Gali, and Avago MGA series, which makes it very easy to now construct a high performance Transverter with fewer devices. A low noise MGA-86563 GaAs MMIC is used for the Transverter receive amplifier, guaranteeing performance and requiring no input matching.


A range of oscillator multiplier and amplifier filter Kits are available for either construction of multipliers for transverter local oscillators, Beacons, or ATV transmitters.

  • EME5.8G-MLT KIT1 5800MHz Frequency Multiplier Kit ( suitable for RX only Converters )
  • EME5.8G-AMP KIT1 5800MHz Filter Amplifier Kit ( Used with the EME5.8G-MLT KIT1 for extra L/O filtering. )

The 5800MHz Multiplier Block Diagram shows which Kits products are required and typical gain and power levels.


The pictures show the EME5.8G-MLT KIT that uses a 3/4" od pipe cap and 2x GALI-39 devices. Kits after May 2016 now use Nibco 5/8" od pipecaps.


The EME5.8G-CV7 Kit is a simple Up / Down Converter block that can be used as the basis to construct a complete Transverter, or Receiver only converter.

The pictures show the basic 9cm ( 3400MHz ) Transverter with a low noise MGA86563 receive device and single pipe cap filter. The output of the mixer shows a 144MHz diplexer that can be changed to 430MHz by replacing with a simple resistor attenuator for mixer termination. The Mixer is a Mini-Circuits MCA1-85 that has a wide 2800 to 8500MHz frequency range. The Transverter can be tuned to be used between 2700 and 4500MHz for various other applications.


The EME5.8G-DRV Kit 1 has been designed to be used in conjunction with the EME5.8G-CV7 Kit to produce around +13dBm output on TX. The Kit can also be used as a general purpose filter amplifier with +32dB gain, and a +20dBm @ 1dB compression output.

EME141-5800 PA KIT

The EME141-3400 Kit is a modern High Performance 3.4GHz 2 Watt Power Amplifier that uses the TC3341 PHEMT MMIC, & a high efficiency switching power supply. The PA is suitable for linear & non linear modes, including SSB & FM Television.

What other Components are required:

A number of other Kits & Components are required to construct a complete transverter. For the 592 / 624MHz Local Oscillator, the EME175 Kit can be used. The EME177 Heater Kit is high recommended when used with the 60 degree C Crystals from Mini-Kits For more information on the EME175 oscillator, & EME177 Heater Kits please see the EME175 Kit webpage.

For sequencing & switching of the RF & power supply voltages the EME166 Sequencer Kit is highly recommended. The EME166 shown allows a single I/F Transverter connection.

For low power Antenna switching, the EME144 Relay Kit is ideal & will handle a few watts of RF at 5800MHz.

For a Power Amplifier the EME141-5800 Kit can be used that will produce up to 1Watt output on 5800MHz.

Cable & connectors can be found on the website. The SMA PCB mount connectors used on the EME5800 series Kits are part number SMA36.

Changes & Modifications

1/ After May 2016 all of the the EME5.8G Kits now use a Nibco 5/8" od pipecap which replaces the 3/4". Both pipecaps are a similar height so the tuning range is about the same.
