The complete 23cm Pluto Charon module has a fixed frequency range of 1210 to 1310 MHz and is suitable for all mode SSB or FM operation,  and is constructed on a professionally etched 78x65mm FR4 PC Board.  The design incorporates a  high gain transmit amplifier with up to +36dB 4 watts output, and a low noise BGU8051 amplifier for a <1.5dB NF.  Ceramic filters are used for filtering on both the transmit and receive amplifiers, and an onboard relay is used for antenna switching making the module a complete solution for portable operation.  The Pluto Charon module requires a Adlalm PLUTO SDR, Pluto PTT module, and modified firmware.  This module is not suitable for full duplex operation.

Refer to the Adalm PLUTO webpage for more information on what is required.

EME242-23CM KIT is a basic Kit that includes the PC board, construction notes, and all on board components and heat-sink. No connectors or enclosure are included. Requires complete construction and soldering of small SMD components.

EME242-23CM MOD is a built and tested module board with sma connectors.  Limited Availability when we have one in stock.

Fan 40x40mm ceramica 12v option is recommended for continuous FM operation. It requires 2x PP-M4x30 screws to attach to the heat-sink.

Basic Kits Do Not include connectors, miscellaneous hardware, enclosure etc.  Metal working skills and tools are required including a M2.5 Tap for the heat-sink threads.

This Kit is for very advanced constructors only, as it uses a very high number of small SMD components and requires high skill.
