Home made RF power amplifier for six meter band

Whether we are tuning up homebrew equipment, checking antenna VSWR, adjusting a linear amplifier, or just monitoring output power during a contest, almost all aspects of ham operation can use a power meter. Paul Wade W1GHZ

This homebrew six-meter linear amplifier started off life as a "junker" Alpha 76PA h.f. amplfier. Power output is 800W

The circuit is based on two AD8307 log amplifiers, which are connected to the forward and reflected ports on a directional coupler

Offer a wide range of homebrewing projects mainly for VHF UHF operations. From vhf antennas to preamplifiers, chargers and power supplies

There is not a personal design on this page, just I've transfered useful notes from PHILIPS RF Bipolar Transistors - Data HandBook about BLY89C VHF Power transistor, which is very popular among Amateur Radio homebrewers

Homebrew Tubes/LDMOS amplifiers, Antenna, accessories, adventures in 9Q, DX, UN missions, Contests, and more.

A 144MHz FM class C RF Power Amplifier based on a 2N6084 RF transistor, that can produce 50w output max

The SB-200 Sleeper a 1KW RTTY-duty Contest Amplifier

Thoughts build a solid state legal-limit amplifier for amateur radio use.

A combined 1KW VHF, 500W UHF linear power amplifier homebrewed by M0VKK

This project describes a DIY all band HF SDR transceiver. Built around a Softrock 6.3 kit, it boasts a 20W homebrew amplifier and ATmega168 microcontroller for USB control. An LCD displays frequency, power, and SWR. Automatic LPF selection and SWR protection enhance functionality. Compatible with Rocky and PowerSDR software, this project provides a cost-effective and powerful HF SDR transceiver for hobbyists.

This will show you how to add a RF power amplifier to your Proxim Symphony for under $50. The cost is reduced by using the existing components on the Symphony, such as the PIN diode switch, and just inserting a higher power final amplifier. Increase the RF output power of your wireless network card to 1 Watt.

This page, authored by VU2ESE, delves into the sBitx, a Software-Defined Radio (SDR) designed for homebrewers. The content covers the hybrid SDR circuit, software, user interface, hacking/modifying the sBitx, performance, and more. It explores the various components of the sBitx, including the exciter, filters, amplifiers, digital circuit, and modems. The page aims to provide information and guidance for hams interested in building their own SDR. Readers will learn about the capabilities, features, and adaptability of the sBitx, making it a valuable resource for DIY radio enthusiasts.
