FM Power Amplifier BLY87A, BLY89A, KT920A, KT925B
A very simple fm power amplifier which can deliver 4W rf power with 12V power supply and BLY87A or KT920A and 20W with BLY89A or KT925B.
If you use BLY87A or KT920A the input power must be 0.5W and 4W if you use BLY89A or KT925B. This fm power amplifier is designed to work on [...]
Stun Gun simple schematic
This is a simple stun gun circuit schematic just for learning! In No Way Do I Recommend Building these Stun-Guns or the actual use of them for any purpose what so-ever.
We will present more stun gun schematics but in no way we recommend you to build it, I Assume NO LIALIBITY for any resulting actions [...]
Fm power amplifier 50W BLY94
This fm power amplifier circuit is built with BLY94 transistor which delivers up to 50W at 175MHz and has a power gain of 7dB, arround 5x power amplification.
But in this schematic bly94 is working in 3 meter band, FM 88-108 MHz, so it has a higher power gain, 8dB - 6x. So if we use [...]
