Transistor Radio Circuit
This three-transistor AM radio circuit is a clean and minimalistic design, and it faithfully amplifies radio signals so that you can hear them through a loudspeaker. I am using the MPSA13 transistor for this design because internally it is a Darlington and consequently has very high gain.
A transistor radio is a small portable radio receiver that uses transistor-based circuitry.Following the invention of the transistor, the first commercial transistor radio was released in 1954. The mass-market success of the smaller and cheaper Sony TR-63, released in 1957, led to the transistor radio becoming the most popular electronic communication device of the 1960s and 1970s.
06/10/2019 · The above design has one drawback, though. The output received from the above circuit would have greater content of sawtooth noise compared to the actual FM reception. A smart technique can be seen employed in the following single transistor FM radio circuit to attribute better efficiency to this simple design.
A one transistor MW/AM radio. Another MW Autodyne Receiver. I knocked up this circuit as it claims so much (there is a version with a speaker transformer that claims loud speaker performance from two transistors) and is so simple:
17/08/2009 · Description. Here is the circuit diagram of a simple radio that uses one transistor and few other passive components.The C6 and L1 forms a tank circuit which picks up the signal from your desired radio station.Diode D1, capacitor C2 and resistor R1 does the detection of the picked signal.The detected signal is coupled to the base of Q1 through capacitor C3.The Q1 gives required amplification ...
I'm extremely happy with how the 3 Transistor Short Wave Radio looks and how well it pulls in distant stations. How The 3 Transistor Short Wave Radio Works. The 3 Transistor Shortwave Radio in this article is a regenerative radio designed to tune from 2Mhz through 30Mhz depending on the tuning coil used by the operator.
The circuit was designed so as to get the maximum possible gain out of the first three transistors (which operated at radio frequencies). The first transistor used as a frequency converter was operated very close to its V CBO of 30 volts (from the 22.5 volt battery).

Transistor Circuits: different types of transistor circuit There are many different transistor circuits ranging from types like the common emitter and emitter follower to designs like the current mirror, Darlington, Sziklai pair, current mirror, long tail pair, current source and many more .
11/06/2018 · Here is a simple circuit for a one transistor Audion type radio powered by a 1.5 V battery. It employs a set of standard low impedance headphones with the headphone socket wired so that the two sides are connected in series thus giving an impedance of 64 Ω.
