The complete 33cm Transverter has a fixed frequency range of 902 to 928MHz and is suitable for all mode SSB or FM operation,  and is constructed on a professionally etched 80x65mm FR4 PC Board.  The design is no tune so requires no alignment as it uses SAW filters  and is suitable to be used with a 144MHz I/F.  The receiver uses a low noise MGA86563 PHEMT, and the transmit driver amplifier produces up to +20dBm output.  The Transverter can handle up to 5 Watts input from a 144MHz Transceiver as it has an on board attenuator and RF sensing circuit for switching from RX to TX mode. This Kit requires a suitable low noise 758MHz +7dBm Local Oscillator. Currently there is no local oscillator option available.

Refer to the 23cm 1200MHz Transverter Block Diagram for more information on what is required.

THIS KIT IS NOT FOR BEGINNERS AND REQUIRES VERY EXPERIENCED SOLDERING SKILLS

The Product image shows a fully constructed Kit product.  Please refer to the Options Tab for the descriptions of the various products available.

EME227-33CM KIT is a basic Kit that includes the PC board, construction notes, and all on board components. No connectors or enclosure are included. Requires complete construction and soldering of small SMD components.

For 902 to 906MHz select the 96MHz crystal. 

Please refer to the 33cm ( 902-928MHz ) Transverter Block Diagram that will explain in more detail what is required to construct a complete Transverter. Block Diagram to be updated for the 33cm Band

Basic Kits Do Not include connectors, miscellaneous hardware, enclosure, and require other Kit products etc. This Kit is for very advanced constructors only as it uses a very high number of small SMD components
