Transistor Walkie Talkie Circuit Diagram

Transistor Walkie Talkie Circuit Diagram In general, this transistor walkie talkie circuit is the same as other walkie talkie circuit. This transistor walkie talkie circuit, consist of transceiver and audio amplifier parts. But in a walkie talkie circuit, there is an audio transformer, and some are not. Altought different, but both have same function to amplify the audio signal. Transistor walkie talkie circuit diagram Walkie talkie circuit that do not use audio transformer, only use transistor on the audio amplifier, usually consist of four transistor. As for the transceiver circuit, uses only one transistor, but there are also some that use three transistor for more sensitivity. This transistor walkie talkie circuit uses crystal oscillator for frequency stability, while the radio is in transmitter mode. This transistor walkie talkie circuit works the same way as other walkie talkie, that is the change of the circuit during receiver mode and transmitter mode.

Three transistor walkie talkie

This time i will share different walkie talkie circuit. Basically this walkie talkie circuit almost the same as with other walkie talkie circuit. Three transistor walkie talkie It's just that in this circuit using three transistors on the transceiver. Two transistor as receiver and one for transmitter, and the transceiver part is separate. The reason the receiver use two transistors is to increase sensitivity of receiving signals. So the circuit image for this time may be useful.

One transistor walkie talkie

Basically this one transistor walkie talkie circuit, is the same as with other walkie talkie. It's just that in this circuit, some audio amplifier transistor are replaced with audio amplifier ic. It aims to reduce the size of pcb, so that walkie talkie can be made with smaller size. L2= 3t, 2t, 2t One transistor in question is on transceiver only. This section is the most important on a walkie talkie, because this section serves to transmit and receive radio signals. So it can be used to communicate. For an explanation how this walkie talkie works, we will discuss it later.
