100W Transmitter RF Power Amplifier 2SC2782
The 6-meter band RF power amplifier operates at a frequency of 50 MHz, specifically designed to enhance transmission capabilities for amateur radio applications. The amplifier's primary function is to boost the power output to 100W, making it suitable for long-distance communication, particularly in Single Sideband (SSB) modes. The FT-736R transceiver serves as the driving device, providing a 10W input signal that the amplifier further amplifies.
The design incorporates a Toshiba RF bipolar power transistor, known for its reliability and efficiency in RF applications. This choice of transistor is crucial for achieving the desired output power while maintaining linearity and minimizing distortion, which is essential for clear signal transmission.
To facilitate the construction of this amplifier, it is advisable to utilize a double-sided printed circuit board (PCB). This configuration improves grounding and enhances current transfer, which is vital for the performance of high-power RF amplifiers. Additionally, the double-sided PCB allows for better thermal management, reducing the risk of overheating during prolonged operation.
The amplifier's transmit power can be tuned up to 120W, providing flexibility for various operating conditions and enabling the user to adjust the output based on specific communication needs. Fine-tuning the output power can be achieved through appropriate biasing and component selection, ensuring optimal operation within the desired frequency range. Overall, this RF power amplifier is a robust solution for amateur radio enthusiasts seeking to enhance their 6-meter band communication capabilities.This is a 6m band transmitter RF power amplifier (50 MHz) with 100W output. It used with my FT-736R and drive from 10W for the 6m SSB DX. The Building information comes from Japan CQ Magazine. The Toshiba RF bipolar power transistor is used in it. If you want to construct this rf amplifier, it`s the better way if the double side PCB use for increase the grounding and current transfer. The TX power can be tune to 120W. . 🔗 External reference
