Op amp pin diode drivers op amp circuits are an attractive alternative to traditional pin diode drivers.
Pin diode switch driver design.
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.
The carrier lifetime of pin diode i use is 10microseconds typ.
Microsemi s switch drivers contain internal spiking and decoupling capacitors.
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 pin diode is a special diode which can be configured as an rf switch.
Op amp switch drivers is their inherent flexibility.
A good driver may get faster.
Inputs are compatible with standard logic families.
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.
A clear advantage of op amp switch drivers is their inherent flexibility.
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.
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.
They can be easily configured for a variety of applications supply voltages and conditions to provide the designer with a multitude of design options.
Pin diode driver circuits are a pain to design and build.
References 1 2 provide a fuller treatment of this subject and can be used as a basis for rf switch switch driver interface designs.
