DESCRIPTION
These families of high ratio hyperabrupt varactor diodes employ high
energy ion implantation and grown junction epitaxy to provide highly
repeatable C / V functions and the highest Q values available in the
industry. The economical SOT-23 package allows these devices to be
used in a wide range of VHF-UHF and wireless microwave designs. All
are available in single die 23-0 configuration (see configuration sheet).
Other configurations are available - consult factory for availability.
This series of diodes meets RoHS requirements per EU Directive
2002/95/EC. Consult the factory for details.
APPLICATIONS
These devices are ideal for wide bandwidth linear VCO’s from VHF
through 1500 MHz. They are especially well suited for economy
applications that demand ruggedness and repeatability. Straight line
frequency Vs. Voltage functions are realized across mid voltage ranges.
They can also be used in voltage variable filter and phase shifting
applications which demand higher peak voltage handling and lower
distortion by selecting back to back configurations. Consult factory for
availability.
