This file type includes high resolution graphics and schematics. Front-end limiter circuits using Schottky and PIN diodes can provide needed protection in communications and other RF systems ...

The last chapter will provide a trip down memory lane for some readers—a sampling of circuits of particular interest in RF history, including the Regency TR-1 transistor radio design and the ...

A paper by W. J. Polydoroff refers to the advantages, particularly in the matter of selectivity, which result from tuning radio receiver circuits in such a manner that the ratio of tho inductance ...

An important point in connexion with the layout of the whole receiver is to ensure that the local oscillator and the main radio frequency circuits are kept as far away as possible from the power ...

The transmitter was actually a pretty simple circuit, just a crystal-controlled oscillator and an RF amplifier really, but still managed about 1.5 Watts output on the 80-meter ham band.

Implemented in a 65 nm RF-CMOS process, the RF-VCA makes integrating ARM processors, a customer’s proprietary digital circuits and custom RF receivers into small, cost effective solutions a reality.
