This Am radio receiver circuit is based on the TDA1083 radio IC that can be used to build a simple MF band radio . This AM radio schematic circuit based on the TDA1083 will work in 300kHz – 3MHz frequency range .
A very simple VHF antenna amplifier circuit diagram can be designed using this circuit diagram .
This VHF antenna amplifier circuit diagram can be used for a frequency range between 1 and 300MHz.
The VHF antenna amplifier circuit is constructed based on the BFT66 transistor connected in common emitter connection.
This fm transmitter circuit is designed using UPC1651 FM monolithic circuit, that require few external electronic components. This UPC1651 FM transmitter circuit is specially designed as a wide band amplifier covering the HF band trough UHF band .
The circuit has a broad frequency response to 1200MHz and power gain up to 19dB .
