WebbThe characteristics of a signal point contact diode are different for both germanium and silicon types and are given as: 1. Germanium Signal Diodes – These have a low reverse resistance value giving a lower forward volt drop across the junction, typically only about 0.2 to 0.3v, but have a higher forward resistance value because of their small junction area. WebbThis series of diodes can operate up to 6GHz with high-voltage handling capabilities and together with outstanding RF performance, they simplify design-in because of their extreme low forward resistance, diode capacitance and series inductance.

Webb12 jan. 2024 · The resistor limits the current through those clamping diodes to about 0.7 mA. The internal pull-up resistor is of no use as it's between the pin and +5V. You need a resistor between the pin and your actual input, That is not a pull-up resistor. It's a current limiting resistor, a very different function. Webb12 nov. 2024 · PIN diodes. The PIN diode is used as either a switch or an attenuator at RF and microwave frequencies. It is formed by sandwiching a high resistivity intrinsic semiconductor layer between the P-type and N-type layers of a conventional diode; hence the name PIN, which reflects the structure of the diode (Figure 8).
The PIN diode obeys the standard diode equation for low-frequency signals. At higher frequencies, the diode looks like an almost perfect (very linear, even for large signals) resistor. The P-I-N diode has a relatively large stored charge adrift in a thick intrinsic region. At a low-enough frequency, the stored charge can … Visa mer A PIN diode is a diode with a wide, undoped intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor region. The p-type and n-type regions are typically heavily doped because they are … Visa mer PIN diodes are useful as RF switches, attenuators, photodetectors, and phase shifters. RF and microwave switches Under zero- or reverse-bias (the "off" state), a PIN diode has a low capacitance.
