The diode can be used to weaken or totally shut off RF signals and to amplitude modulate a carrier signal. In this rf switch, the PIN diodes are used to shut on of off several antennas. The current ...

This article offers practical guidance in the selection of PIN diodes for switch control circuit functions. Diode parametric language such as Vb, Vf, Ct, Rs, L , θ, must convert into insertion loss, ...

2. This internal view of the PIN diode shows where the anode contact on the chip is wire-bonded to two connection pins. The limiter was built on a 30-mil thick FR-4 printed-circuit board (PCB ...

In the proposed method, every IO pin is connected to every other pin with two switch-and-diode series circuits. Figure 1 shows a two-pin example. In this configuration, switch S1 can be read by ...

PIN diodes are named for a region of undoped intrinsic semiconductor lying between their p and n-type material. This area eliminates capacitance effects between the n and p-type areas that can ...

To illustrate a basic diode switch, we’ve prepared a couple of simplified circuit diagrams. The first shows the anode tied to ground through R1 and the cathode tied to the Vcc power rail.

LEWISVILLE, Texas, March 28, 2018 /PRNewswire/ -- Fairview Microwave Inc., a leading provider of on-demand RF and microwave components, has released a new line of E and W-band PIN diode waveguide ...
