Application Notes & Technical Data
Application Note: Tuning Varactors: Within the general family of tuning varactors, there are several major categories, each designed for particular consideration of application and cost.
Circuit tuning requirements define the appropriate device capacitance versus voltage curve and specific material doping gradients. This application note
covers this topic and includes a mathematical model and discussion on Si vs. GaAs.
- Application Note: PIN Diodes: PIN diodes are primarily used as control devices for both RF and microwave power. The following applications are discussed:
Switches
Attenuators
Phase Shifters
Limiters
Included are design issues of power handling vs. frequency, power handling vs. switching speed, and performance vs. frequency and bandwidth.
Once these values have been determined, the proper diode can be selected, as well as the proper value of the bias resistor.
This application note gives examples on how best to achieve this data.
- Application Notes: Chip and Beam Lead Handling: Chip and beam lead devices are packaged for shipment in either waffle packs or
Gel-Packs®. Chips in waffle packs are somewhat free to move around their wells, and can be accidently dislodged rather easily when the waffle pack is
opened. To prevent this, we recommend the following procedure.
