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.
