Wideband DTV UHF Antenna TV Amplifier Circuit using transistor 2sc3358
This HD TV UHF wideband amplifier (Ultra High Frequency amplifier) provides a total gain of 10 to 15 dB within the frequency range of 400 to 850 MHz, making it suitable for areas with weak television signals. To ensure optimal...
High frequency signal generator
A tapped-coil Colpitts oscillator is utilized at Q1 to deliver four tuning ranges: 1.7 to 3.131 MHz, 3.0 to 5.6 MHz, 5.0 to 12 MHz, and 11.5 to 31 MHz. A Zener diode (D2) is incorporated at Q1 to reduce...
High Frequency Waveform GeneratorCircuit
A high-frequency waveform generator is highly beneficial for electronic experimentation and design. This circuit generates sine wave oscillations; however, it can be modified to produce triangle or square wave functions. The frequency can be controlled using current. By disconnecting the...
