Here I wanted to show a RF balanced modulator circuit that can produce DSB-SC AM signal at the transistor level with all the bias included. This might be helpful if you want to build your own RF balanced modulator at home. One can use readily availa…
I had designed a Differential Amplifier AM Modulator previously and found that I should make some correction to the circuit as an improvement. The differential amplifier AM (Amplitude Modulation) is also called "Long-Tailed Pair" modula…
The 2N3904 transistor is humble, yet incredibly versatile bipolar transistor that can be used in RF projects like building oscillator for SSB AM transmitter. Often overlooked in favor of more specialized (and expensive) components, the 2N3904 truly…
An RF (radio frequency) mixer is an electronic device that is used to combine two or more input signals to produce a new output signal at a different frequency. This process is known as frequency mixing or heterodyning. RF mixers are used in a wide…
