Op amp pin diode drivers op amp circuits are an attractive alternative to traditional pin diode drivers.
Pin diode switch driver design.
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.
Op amp switch drivers is their inherent flexibility.
Inputs are compatible with standard logic families.
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.
A clear advantage of op amp switch drivers is their inherent flexibility.
Because of the complexity of designing a high speed current driver circuit the fet switch typically has an advantage in switching speed as well.
The carrier lifetime of pin diode i use is 10microseconds typ.
Pin diode physics topics such as pin diode forward and reverse bias operating characteristics and.
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.
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.
