DESCRIPTION
The GC1500 series varactors are silicon abrupt junction devices. They offer
the highest Q and lowest series resistance available in a 30 Volt silicon
varactor.
This series of diodes meets RoHS requirements per EU Directive
2002/95/EC. The standard terminal finish is gold unless otherwise
specified. Consult the factory if you have spe cial requirements.
APPLICATIONS/BENEFITS
VHF to Ku Band Tuning
VVF (Voltage Variable Filters)
Phase Shifters
APPLICATIONS
The GC1500 series varactors are used for n arrow to moderate bandwidth
tuning. They are availab le in values appropriate for VHF through KU band
frequencies. These devices are best used in low phase noise voltage
controlled oscillators, low loss voltage variable filters and phase shifters.
Standard capacitance tolera nce is ±10%, other capacitance values and
custom mechanical configurations are also available. All sp ecifications shown
are based on style 30 packag e and include 0.18 pF case capacita nce.
Consult package outline section of this catalog for other case styles available.
Complete electrical and mechanic al data is also provided.

Notes
1) When ordering, specify the desired case style suffix to the model. (eg. GC1501 – 30)
2) Capacitance values include a package capacitance of 0.18 pF. Capacitance is measures at F = 1 MHz.
3) Q is calculated from:
a. Q =
1442/ CjfRs
b. RS is measured using @ 1 GHz using transmission loss techniques.
c. Capacitances is measured at 1 MHz
4) GC1500A is only available in chip form. (GC1500A – 00)
