RF amplifier with 100 dB dynamic range

This amplifier was designed to improve an existing receiver by replacing the original r.f. stage. The circuit utilises a dual gate MOSFET, has a dynamic range of 100 dB, and exhibits low intermodulation distortion over the range lO0kHz to 30MHz. Incorpor• ation of the amplifier into an existing receiver obviously varies, depending on the receiver, and cannot be discussed in detail but must be left to the individual constructor.
