The Mini-Kits EME207 Preselector Filters are part of a building block to construct a high performance M1 Series HF Transceiver.  The module boards are 3 pole mesh capacitor coupled Chebyshev Band pass filters that are modified PA3AKE designs for the HF Ham bands.  The filters are ideal for use with most receiver or transceiver projects that require narrow filters specifically for the Ham bands for good performance.  The design incorporates onboard relays to switch the filters into the RF signal path, and to provide filter isolation by grounding the filter when switched out of circuit.  The modules use stackable headers so that multiple filter boards can be stacked and controlled through the same IDC interface connector for band switching.

For more detailed information on how this module Kit can be used, Please refer to the EME207 Kit webpage

This Kit is ideal for all constructors mainly due to the use of conventional leaded components.  Only a very small number of surface mount components have been used due to component availability.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.
