Pin Diode Switch Driver Design

Infineon pin diodes come with low loss and low distortion levels and are suitable for a wide range of mobile communications and rf applications.

Pin diode switch driver design.

Op amp circuits are an attractive alternative to traditional pin diode drivers. Op amp pin diode drivers op amp circuits are an attractive alternative to traditional pin diode drivers. It has a wide undoped intrinsic semiconductor region i sandwiched between a p type semiconductor p and an n type semiconductor region n hence the pin designation. Driver circuits for high power pin diode switches the information in this chapter is presented as a guide for the rf switch switch driver interface.

A clear advantage of op amp switch drivers is their inherent flexibility. They can be easily configured for a variety of applications supply voltages and conditions to provide the designer with a multitude of design options. Because of the complexity of designing a high speed current driver circuit the fet switch typically has an advantage in switching speed as well. Op amp switch drivers is their inherent flexibility.

This 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. Pin diode switch driver examples. The subject of driver circuits for pin diode switches and attenuator circuits is always relevant to any practical component design and thus has been included in a separate appendix. Pin diode driver circuits are a pain to design and build.

A good driver may get faster. Pin diode physics topics such as pin diode forward and reverse bias operating characteristics and. Microsemi s product line of pin diode switch driver modules is designed for use in applications where gaas or fast speed si pin diodes are utilized. External negative supply voltages may be as high as 18 volts.

There are some great vendors out there that can supply you with many types of pin switch drivers commercial. References 1 2 provide a fuller treatment of this subject and can be used as a basis for rf switch switch driver interface designs. I have read some ap notes of pin diodes and got to know that switching speed of my antenna switch is not only related to carrier lifetime of pin diodes but also related to driver. Part number is um4010 manufactured by microsemi corp.

Microsemi s switch drivers contain internal spiking and decoupling capacitors. The pin diode is a special diode which can be configured as an rf switch.
