DESCRIPTION

The EME3400 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 3400MHz can be easily constructed using a number of Kits & components available from Mini-Kits. The picture below shows a prototye chassis with a fully working transverter for 3400MHz.

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 EME3400 series Kits require +9 volts, so that they can easily be used for portable battery operation. Only the EME3400-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 EME3400 series Kits use modern low noise high gain amplifiers, including the Mini-Circuits Gali, & 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 & requiring no input matching.

EME3400-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.

• EME3400-LO KIT1 3400MHz Multiplier Kit ( suitable from RX only Converters )
• EME3400-LO KIT2 3400MHz Filter Kit ( Used with the EME3400-LO KIT1 for extra L/O filtering. )
• EME3400-LO KIT3 3400MHz Filter Amplifer Kit ( suitable for Beacon transmitters )

The 3400MHz Multiplier Block Diagram shows which Kits products are required & typical gain & power levels.

EME3400-TRV KIT

The EME3400-TRV Kit is a simple Transverter block that can be used as the basis to construct a complete Transverter, or Receiver only converter.

EME3400-TX KIT

The EME3400-TX Driver Kit has been designed to be used in conjunction with the EME3400-TRV Kit to produce around +13dBm output on TX. The Kit can also be used as a general purpose filter amplifier with +32dB gain, & a +20dBm @ 1dB compression output.

EME141-3400 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 651.2MHz 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.

For low power Antenna switching, the EME144 Relay Kit is ideal & will handle a few watts of RF at 3400MHz.

For a Power Amplifier the EME141-3400 Kit can be used that will produce up to 2Watts output on 3400MHz.

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.
