The Mini-Kits EME204 9MHz IF AGC Amplifier Kit is part of a building block to construct a high performance M1 Series HF Transceiver. The module board incorporates a 9MHz high gain amplifier with automatic gain control, AM demodulator, and S-meter circuit. The circuit design is based on older Transceiver designs from the mid to late 1980's that were analogue in design, but we have used modern BF904 MosFETs that are specifically designed for AGC applications, to improve the AGC performance especially with strong signals. This module has been specifically designed as a building block for the Mini-Kits M1 Series HF Transceiver, but is 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 EME204 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.
EME204 KIT is the Basic Kit that only includes the PC board, Instructions, and on board components. Requires complete construction, and soldering of some SMD components.
2 x SMA39 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.
Hammond 1590BBFL enclosure or similar is required to fully shield the module board from other RF circuitry.
PC boards are not available separately as this Kit uses a number of specialized components that are not easily obtainable in low quantities.
Kits Do Not include miscellaneous hardware, enclosure, or RF connectors, but do include the 2.54mm on board headers.
