2M Fet Power Amplifier Circuit
Using a power MOSFET, this amplifier can achieve a 2-W handheld radio power level, increasing it to approximately 10 W on the 2-meter band. A transmission-line RF switch is employed for transmit/receive (T/R) switching.
The described amplifier utilizes a power MOSFET...
300w power amplifier circuit with 2n773
This amplifier was designed to utilize the otherwise unused TO3 power transistors that many hobbyists possess. With proper construction, the module can achieve high-quality performance and is rated for 300 watts into a 4-ohm load, depending on the power supply....
Composite CPI amplifier
B is a pure output Class B mode power amplifier. The preamplifier input section of the circuit does not utilize a conventional differential input circuit; instead, it employs a single-ended input. This design features a single-ended output Composite CPI, which...
Pre-dividing power amplifier
An active high-power tube operates in the MHz range, priced around 3 to 4 yuan, with a transition frequency (fT) exceeding one-fifth of 50 MHz for similar power tubes. This circuit is designed for high reliability in low-frequency high-power amplifier...
Dual Power Amplifier Using TDA7293 MOSFET IC
As readers may know, there are several power amplifier projects, including two that utilize integrated circuit (IC) power amplifiers, commonly referred to as power op-amps. Both of these projects have gained popularity, and this new project is not intended to...
Amp Circlotron
It is a power amplifier configuration developed in the 1950s, known as a circlotron due to its original diagram being drawn in a circular shape. The best representation available is a bridge format. Its primary advantage is very low distortion....
