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.
EME207-KIT is the Basic Kit that only includes the PC board, Instructions, and on board components. RF Connectors are Not included. Requires complete construction, and soldering of some SMD components.
EME207-PCB is the bare PC Board only and does not include any documentation or components. ( Not Recommended as the components are not readily available )
2 x SMA33 connectors are recommended to use with inter wiring of the module board Kits.
1 x IDC16S connector is recommended to use with inter wiring of the module board Kits.
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 connectors.
