BFY51 RF DRIVER

N0FN , Jun 22, He confirms that every newly installed IRF must be individually biased — because they are indeed all different. I have a copy somewhere if you can’t find it elsewhere. We were still interested to learn more about the biasing of the IRF, so googled around, and came upon a forum in which the whole thing was explained in much lucid detail by Paul NA5N: High oltage Switching Features:

Product specification Supersedes data of Aug The information presented in this document does not form part of any quotation or contract, is believed to be accurate and reliable and may be changed without notice. I have been getting 5 to 7 watts out of this combo. Designed for use in general purpose power amplifier and switching applications.

Until the next thing goes wrong. N0FNJun 22, Because this was a test rig, we also took away the Zener diode on the gate, which is apparently only there to protect the gate from excessively high voltages from the driver stage.

It died, innocent as a new-born lamb, in performing its simple task of being a switch. This has a 2N crystal oscillator with transformer coupling, into a 2N driver with a tuned output.

These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not rd. Benefit is lower component count, internal compensation for temperature and current gain spread.

A linear amplifier 1. The Norcal QRP club published a 5 watt amp circuit 15 years ago.

This was fascinating, so we dug out another IRF we had cooked up many times months ago, and put that one in to test it. NPN transistors Applications Audio, general purpose switching and amplifier transistors Description The devices are manufactured in Planar technology with. I’ve seen them in some ‘cheapie’ cb rigs churning a good few watts out at 27mhz! To make this website work, we log user data and share it gf processors.
