30 Volt Abrupt Junction Tuning Varactors
RoHS Compliant
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 special requirements.
KEY FEATURES
Highest Q
Lowest Rs
Large selection of capacitance values to chose from
Low phase noise
RoHS Compliant1
1 Most or our devices are supplied with Gold plated terminations. Other terminal finishes are available on request. Consult factory for details.
APPLICATIONS
The GC1500 series varactors are used for narrow to moderate bandwidth tuning. They are available 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 tolerance is ±10%, other capacitance values and custom mechanical configurations are also available. All specifications shown are based on style 30 package and include 0.18 pF case capacitance. Consult package outline section of this catalog for other case styles available. Complete electrical and mechanical 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 = 1/ 2fRs4Cj4
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)
