Product details
Overview
GC15006-00 from Microsemi is a frequency-linear tuning varactor diode designed for high-linearity voltage-controlled oscillators (VCOs) and RF filters operating through Ku-band. It delivers 0.7 pF capacitance at −4 V, 0.14 pF at −20 V, 13:1 tuning ratio, 0.11 sensitivity, and 1200 typical Q at 4 V / 50 MHz - enabling octave-spanning linear tuning without external compensation in satellite transceivers and radar front-ends.
For engineers reviewing the GC15006-00 datasheet, GC15006-00 pinout, GC15006-00 application, or GC15006-00 equivalent, key selection criteria include its guaranteed 13:1 CJ0/CJ20 tuning ratio, low surface noise for FM-noise-sensitive VCOs, RoHS-compliant gold-plated terminals, and suitability for hybrid microwave assemblies requiring stable C-V linearity above 12 GHz.
Technical Context
The GC15006-00 employs computer-controlled grown junction epitaxy to achieve precise hyperabrupt doping profiles, yielding near-ideal voltage-to-capacitance linearity across its 0–20 V reverse bias range. Its mesa structure and superior passivation ensure low leakage (<50 nA at 20 V) and minimal surface-generated phase noise.
This FLTVAR™ device operates from −55 °C to +125 °C and maintains functional performance through Ku-band (12–18 GHz), with tuning linearity validated under 20 V bias - distinguishing it from standard abrupt or hyperabrupt varactors that require external linearization networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CJ @ −4 V | 0.7 pF ±10% - sets center-frequency anchor point in VCO tank circuits |
| CJ @ −20 V | 0.14 pF typical - enables wideband tuning span up to 13:1 ratio |
| Tuning Ratio CJ0/CJ20 | 13:1 typical - supports octave-plus frequency coverage without calibration |
| Sensitivity (S) | 0.11 - defines dC/dV slope for predictable modulation response |
| Q @ 4 V / 50 MHz | 1200 typical - minimizes insertion loss and phase noise in resonant circuits |
| Max Leakage @ 20 V | 50 nA - ensures stable bias point and low DC power consumption |
| Operating Temp | −55 °C to +125 °C - qualified for aerospace and defense environmental stress |
Pinout & Package
GC15006-00 is supplied in Package Style 00: bare die chip form for hybrid circuit mounting. No discrete package pins; two terminals - anode and cathode - are accessed via wire bond pads on the silicon mesa structure. Terminal finish is gold per standard RoHS compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar varactor tuning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GC15007-00 | Same S = 0.11, but CJ(−4 V) = 1.0 pF and CJ(−20 V) = 0.2 pF - higher baseline capacitance, same tuning ratio | Better suited for lower-frequency VCOs (X-band) where higher CJ improves tank impedance match | Select GC15007-00 when designing for 8–12 GHz operation with ≥1.0 pF required tank capacitance |
| GC15001-00 | S = 0.08, CJ(−4 V) = 0.7 pF, CJ(−20 V) = 0.2 pF, 8:1 tuning ratio - lower sensitivity, reduced tuning span | Optimized for narrowband, ultra-low-noise VCOs where linearity over smaller range suffices | Choose GC15001-00 only if system requires <8:1 ratio and prioritizes maximum Q (1400) over tuning width |
Compared with GC15001-00 and GC15007-00, the GC15006-00 uniquely balances 13:1 tuning range, 0.11 sensitivity, and 1200 Q - making it the optimal choice for Ku-band VCOs demanding both wide sweep and low phase noise without linearization circuitry.

FAQ
What is the primary function of the GC15006-00 in RF circuits?
The GC15006-00 functions as a frequency-linear tuning varactor diode, providing voltage-controlled capacitance for VCOs and tunable filters. Its 0.11 sensitivity and 13:1 CJ0/CJ20 ratio enable octave-spanning linear tuning in Ku-band applications without external linearization - a capability confirmed in Microsemi's FLTVAR™ characterization data for the GC15006-00.
Does the GC15006-00 require special handling during assembly?
Yes - the GC15006-00 is ESD-sensitive and must be handled using Class 1A ESD precautions per Microsemi's documentation. Its bare-die Package Style 00 form also requires controlled atmosphere wire bonding and gold-to-gold interconnect processes to maintain low leakage (<50 nA) and surface noise integrity in final assembly.
What is the maximum reverse voltage rating for the GC15006-00?
The GC15006-00 has a maximum rated reverse voltage of 22 V, verified in Microsemi's absolute maximum ratings table. Operation beyond this voltage risks junction breakdown and permanent degradation of C-V linearity and Q factor - the GC15006-00 must be biased strictly within 0–22 V for reliable performance.
Is the GC15006-00 RoHS compliant?
Yes - the GC15006-00 meets EU Directive 2002/95/EC RoHS requirements, with standard gold terminal finish. Microsemi explicitly states RoHS compliance for the entire GC15000 series, including the GC15006-00, and confirms suitability for lead-free reflow assembly in hybrid microwave circuits.
How does the GC15006-00 differ from standard hyperabrupt varactors?
The GC15006-00 uses computer-controlled grown junction epitaxy to achieve superior C-V linearity (S = 0.11) and higher Q (1200) versus ion-implanted hyperabrupt diodes. Unlike generic hyperabrupt parts, the GC15006-00 guarantees 13:1 tuning ratio and low surface noise - validated in Microsemi's Ku-band VCO noise measurements for the GC15006-00.
