Product details
Overview
GC15010-00 from Microsemi is a frequency-linear tuning varactor diode designed for high-performance VCO and filter tuning in Ku-band RF systems. It delivers 10.0 pF capacitance at −4 V, 2.0 pF at −20 V, 13:1 tuning ratio (CJ0/CJ20), 0.11 sensitivity, and 700 typical Q at 4 V / 50 MHz - enabling octave-wide linear tuning without external linearization in satellite transceivers and radar front-ends.
For engineers reviewing the GC15010-00 datasheet, GC15010-00 pinout, GC15010-00 application, or GC15010-00 equivalent, this page provides verified electrical parameters, package mapping to Style 00 (chip-on-carrier), Ku-band frequency response, low-phase-noise design value, and direct alternatives with documented C-V curve and Q trade-offs.
Technical Context
The GC15010-00 employs computer-controlled grown junction epitaxy to achieve precise hyperabrupt doping profiles, yielding a voltage-dependent capacitance slope (sensitivity = 0.11) optimized for linear frequency vs. bias behavior across 12–18 GHz. Its mesa structure and superior passivation minimize surface leakage and trap-related noise.
This device operates over −55 °C to +125 °C with ≤50 nA leakage at 20 V reverse bias and supports stable tuning up to Ku-band frequencies due to its high Q (700 @ 4 V/50 MHz) and low parasitic contribution when mounted on low-capacitance carriers.
Key Specifications

Pinout & Package
GC15010-00 is supplied in Package Style 00: a bare silicon chip mounted on a ceramic or metal carrier for hybrid microwave assembly. No discrete leads or solder pads - terminals are accessed via wire bonding to anode and cathode metallization areas.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward-biased terminal | DC bias injection point; requires series resistor to limit current during tuning |
| Cathode | Reverse-biased terminal | AC-grounded node in VCO tank; must maintain low-inductance RF return path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar frequency-linear tuning varactor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GC15009-00 | CJ = 5.0 pF @ −4 V; Q = 800; sensitivity = 0.11; tuning ratio = 13:1 | Nominal center frequency ~1.4× higher than GC15010-00 in identical tank layout | Select when targeting 15–22 GHz operation with tighter capacitance tolerance |
| GC15011-00 | CJ = 22.0 pF @ −4 V; Q = 500; sensitivity = 0.11; tuning ratio = 13:1 | Lower Q increases phase noise but improves low-frequency tuning linearity below 10 GHz | Choose for sub-12 GHz VCOs where capacitance headroom outweighs Q penalty |
Compared with GC15009-00 and GC15011-00, GC15010-00 strikes a balance between mid-band capacitance (10.0 pF), usable Q (700), and Ku-band linearity - making it optimal for 12–18 GHz VCOs where both tuning range and spectral purity are critical.

FAQ
What is the maximum reverse bias voltage for GC15010-00?
The absolute maximum reverse bias voltage for GC15010-00 is not explicitly specified beyond the test condition of 20 V used for leakage measurement. However, the device is characterized up to −20 V for C-V and Q measurements, and operation above this voltage risks irreversible junction breakdown. For reliable long-term use, GC15010-00 should be biased within 0 to −20 V, with derating recommended above 85 °C ambient.
Does GC15010-00 require special handling due to ESD sensitivity?
Yes, GC15010-00 is classified as ESD-sensitive per the manufacturer's documentation. It must be handled using standard Class 1A ESD precautions - including grounded workstations, conductive flooring, wrist straps, and static-dissipative packaging - to prevent latent damage to the epitaxial mesa junction, which could degrade leakage current or C-V linearity.
Is GC15010-00 RoHS compliant?
Yes, GC15010-00 meets RoHS Directive 2002/95/EC requirements. The standard terminal finish is gold, and all materials used in the GC15000 series - including die attach, passivation, and carrier substrate - are RoHS-compliant. Full compliance documentation is available upon request from Aetrix Electronics.
What package style does GC15010-00 ship in by default?
GC15010-00 ships in Package Style 00 - a bare silicon chip mounted on a ceramic or metal carrier for hybrid microwave assembly. This configuration minimizes parasitic capacitance and preserves C-V linearity at high bias voltages, unlike packaged variants such as Style 17 or 450A which add parallel capacitance detrimental to Ku-band performance.
How does the 0.11 sensitivity value impact VCO design with GC15010-00?
The 0.11 sensitivity value means GC15010-00 exhibits a near-constant dC/dV slope across its tuning range, resulting in linear frequency vs. control voltage behavior in properly designed VCOs. This eliminates need for lookup tables or analog compensation networks, simplifying loop filter design and improving settling time in frequency-hopping systems using GC15010-00.
