The 50MHz Assistant
The preamplifier is the most important part of the whole unit, due to it being a narrowband amplifier it is mandatory in order to avoid receiver front-end overload especially that caused by nearby TV
The SID Seizer is a VLF/LF receiver
The SID Seizer is a VLF/LF receiver project for monitoring Sudden Ionospheric Disturbances, typically caused by solar flares
U301 FET preamplifier
This FET preamplifier has been around for almost 25 years. It is extremely reliable and can handle several watts directly into either the input or the output without failur
Ultra High IP3 LNA 144 MHz
Was equipped with an ultralinear low noise monolithic amplifier pga-103+
Wideband PreAmp's for HF/VHF/UH
This MMIC is designed for use as a general purpose 50 W gain block. Applications include narrow and broad band IF and RF amplifiers in commercial and industrial applications
