Radio circuits electronic circuits design projects
Radio circuits electronic circuits design projects and schematics various transmitters, receivers, rf amplifiers, rf boosters and other similar radio circuits.
Using the MC3335P low power narrow band FM receiver can be designed a very simple 80m SSB receiver circuit using few electronic parts.
The 80m SSB receiver circuit is very simple, requiring few external components and it includes a simple audio power amplifier based on a LM386 audio IC .
This long range FM transmitter electronic project is a very simple and powerful transmitter circuit with a range up to 1 kilometer in open air.
This long range FM transmitter uses an RF transistor in its output stage and two BC547’s for the first two stages.
The circuit is basically a radio frequency oscillator that operates around 100 MHz.
This antenna amplifier is very useful for 35kHz-150Mhz frequency band . This antenna amplifier circuit is based on transistors and has a low 3dB non-linearity and a high gain of 43 dB .
The input and output impedance for this rf amplifier circuit is 75 ohms.
