Pin Diode Switch High Power

Our silicon heterolithic microwave integrated circuit hmic pin diode process is ideal for high power and broadband switches operating from 50 mhz to 26 ghz.

Pin diode switch high power.

The mm5120 is an ideal solution for replacing large high power rf electromechanical relays as well as rf microwave solid state pin diode switches where linearity and insertion loss are critical parameters. Our algaas pin diode process can extend the upper frequency range of our switch die beyond 70 ghz and is ideal for instrumentation and radar applications. With high isolation low loss and low distortion characteristics the hum2010 hum2015 and hum2020 pin diodes offer low forward bias resistance and high zero bias. Pasternack s spdt high power pin diode rf switches offer desirable performance for transmit and receive signal routing applications with input cw power handling hot switching capability up to 150 watts and high isolation levels up to 75 db typical.

Thus a pin diode is a dc controlled high frequency resistor and if no dc current is present the diode is just like an open circuit. What is the frequency range of the pin diode as an rf switch. Integrated high voltage generation simplifies usage when only a single low voltage is required for operation. It is primarily a function of the thickness of the i region and thicker diodes can operate down to 1 mhz while thinner ones can function into.

Frequency coverage ranges from 20 mhz up to 2700 mhz. It is a silicon semiconductor diode in which a high resistivity intrinsic i region is sandwiched between a p type and n type region.
