The PIN diode’s junction resistance, Rj, can be changed from high to low by applying a forward bias current. PIN diodes can be used either in series or shunt switching mode.

Devices called “PIN diodes” are commonly used as variable dynamic resistances in variable attenuators for RF and microwave applications. Driven to conduct such and so many milliamperes DC, they can ...

When the PIN diode is biased forward (ON), the antenna operates as a loop antenna, while when the PIN diode is biased backward (OFF), the antenna works as a PIFA. The characteristics of the antenna, ...

Checkout how high voltage diodes are constructed, diodes detecting ionising radiation, and finally this great series about our new favourite two-terminal device.

PIN diodes, which sandwich a lightly doped intrinsic (I) region between heavily doped P and N regions, are used extensively in RF and microwave applications. Common applications of PIN diodes are ...

A novel PIN diode concept is said to achieve 10 to 50 times better isolation than a typical PIN diode. The RF PIN diode as we know it today was invented by J. Nishizawa in 1950. Now, almost 70 years ...

A novel PIN diode concept is said to achieve 10 to 50 times better isolation than a typical PIN diode.

This PIN diode rf switch is the ideal antenna switch for VHF and UHF and work with the PIN diodes which are special high frequency switching diodes with very low internal capacitance. The internal ...

This paper describes the development of a heterojunction AlGaAs/GaAs PIN diode as a replacement for the homojunction GaAs PIN diodes commonly used in microwave systems as a control element for ...
