EME5800 SERIES KITS
 Saturday 31st Dexember 2011

 

A complete 5800MHz Transverter can be constructed using a number of 5800MHz series kits that use the EME171 Universal Microwave PC board. The solution is a low cost way to easily construct a transverter. Currently only Kits to construct the local oscillator multiplier are available.

DESCRIPTION

The EME5800 Series of Kits are constructed using the EME171 Universal Microwave PC board. This board greatly reduces the cost to produce various Kits, & allows the constructor to change the design to suit their own application. The Kits can be used to construct local oscillator multipliers, receiver converters, transmit amplifiers & transverters.

A complete Transverter for 5800MHz can be easily constructed using a number of Kits & components available from Mini-Kits. A Transverter Kit is currently not available.

The use of Cavity filters using pipe-caps have been used by Hams for many years, & make excellent filters that can be easily adjusted in frequency & bandwidth. They also allow relatively narrow filters to be constructed which more effectively filter harmonics & 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.

The EME5800 series Kits use modern low noise high gain Mini-Circuits Gali amplifiers, which makes it very easy to now construct microwave circuits with fewer devices.

EME5800-LO KIT

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

  • EME5800-LO KIT1 3400MHz Multiplier Kit ( suitable from RX only Converters )
  • EME5800-LO KIT2 3400MHz Filter Kit ( Used with the EME3400-LO KIT1 for extra L/O filtering. )

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

WHAT OTHER COMPONENTS ARE REQUIRED

A number of other Kits & Components are required to construct a complete transverter. For the 592MHz Local Oscillator, the EME175 Kit can be used. The EME177 Heater Kit is high recommended when used with the 60 degree C Crystals from Krystally. 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 EME66 Sequencer Kit is highly recommended. The EME66 shown above as been modfied to suit the single I/F Transverter connection. Please refer to the EME66 Kit website on how this is done.

Cable & connectors can be found in the catalogue section 3. The SMA PCB mount connectors used on the EME3400 series Kits are part number SMA36.
