The RF probe circuit described here is suitable for signals with the frequency range from about 100 kHz to 1000 MHz. Although the diode used here can, in principle, go up to 3 GHz, the impedance of ...

In other words, hold one end of the diode in the middle, waggle the other end high or low. Particularly for RF circuits you will also find RF chokes in the bias lines to stop RF finding its way ...

In this rf switch, the PIN diodes are used to shut on of off several antennas. The current source is a 12 volt circuit composed of a transformer, bridge rectifier and a regulator IC. In order to know ...

Front-end limiter circuits using Schottky and PIN diodes can provide needed protection in communications and other RF systems. However, designers still must deal with the upper-frequency limit ...

The first source of entropy is a typical avalanche diode circuit, which is formed by a pair ... unique is a second entropy source: a CC2531 RF receiver. The RF receiver continuously skips around ...

A design of voltage doubler circuit has been studied in context of electromagnetic ... For this it is necessary to use a non-linear element (a diode) to convert the RF signal to a DC electrical signal ...

can overcome the low-power limitations of charge-based rectifiers and eliminate antenna and matching circuits. They can convert RF signal energy to a DC signal due to the spin-diode effect ...
