The Mini-Kits EME203 9MHz Crystal Filter Kits are part of a building block to construct a high performance M1 Series HF Transceiver. Filters are available for either a 5 pole or 8 pole crystal filter, and incorporates SPDT switches to either isolate the filter, or switch it in for either the RX or TX signal paths. Multiple filter boards can be stacked using extended header connectors, and controlled through a single 16 Pin IDC header connector, making it easier to interface to logic circuitry.  The design incorporates Analog SPDT FET switching to allow the filter to be used in both the receiver and transmitter circuits.  The filters have been specifically designed as a building block for the Mini-Kits M1 Series HF Transceiver, but are also ideal to construct you own Receiver or Transceiver design.

For more detailed information on how this module Kit can be used, Please refer to the EME203 Kit webpage. Filter Kits are supplied with matched sets of crystals to within 20Hz for the SSB or CW and 50Hz for the AM filters.

This Kit is ideal for most constructors, but does contain a number of surface mount components which have been used to reduce the cost of the Kits.  The basic Kit includes the PC board and all onboard components, but excludes the SMA connectors which can be purchased separately if required.

For the highest performance and reliability, Only high quality first grade components from large suppliers in the USA, or direct from major manufacturers are used in this Kit.

9M-8-2.5k-KIT is the Basic 9MHz 8 Pole 2.5kHz @ 6dB Filter Kit that includes the PC board, Instructions, all on board components, stackable headers, and 8x matched crystals. Requires complete construction, and soldering of some SMD components.

9M-5-6.0k KIT is the Basic 9MHz 5 Pole 6kHz @ 6dB Filter Kit that includes the PC board, Instructions, all on board components, stackable headers, and 5x matched crystals.
Requires complete construction, and soldering of some SMD components.

9M-8-0.5k-KIT is the Basic 9MHz 8 Pole 0.5kHz @ 6dB Filter Kit that includes the PC board, Instructions, all on board components, stackable headers, and 8x matched crystals. Requires complete construction, and soldering of some SMD components

EME203-PCB is the PC board and Instructions Only, ( Not recommended as the components are not readily available )

4 x SMA33 connectors are recommended to use with inter wiring of the module board Kits. Only required on the first filter board as additional boards are stacked using stackable headers.

1 x IDC16S connector is recommended to use with inter wiring of the module board Kits. Only required on the first filter board as additional boards are stacked using stackable headers

4 x SPA-M3x12 used to stack filter boards and match the height of the stackable headers.

Kits Do Not include miscellaneous hardware, enclosure, or RF connectors.
