GC15011-00

Overview

The GC15011-00 is a silicon epitaxial mesa Frequency Linear Tuning Varactor (FLTVAR) designed for wideband linear tuning in VCO and filter applications. It operates with a maximum leakage current of 50 nA at 20 volts and supports an operating temperature range from -55°C to +125°C. Key electrical parameters include a minimum breakdown voltage of 22V, a capacitance of 22 pF at -4V bias, and a typical capacitance of 4.1 pF at -20V bias. The device exhibits a sensitivity of 0.11 and a typical Q factor of 500 at 4V and 50 MHz.

Feature Summary

• Provides wideband linear tuning characteristics suitable for octave tuning without external linearization.
• Features superior passivation for high reliability, low leakage current, and low surface noise.
• Delivers exceptional Q values that result in low FM noise in VCO applications.

Applications

• Voltage Controlled Oscillators (VCOs)
• Filters
• Modulators
• Amplifiers

Procurement Notes

Verify the specific package style required for your design, as the base model number corresponds to chip-style packages intended for hybrid circuits. Confirm RoHS compliance status and terminal finish details directly with the manufacturer or authorized distributors, as these specifications may vary based on production batches and special requirements.

Selection Notes

Select this component when frequency linearity is critical for maintaining constant sensitivity in modulated VCOs. Ensure the circuit design accommodates the specified capacitance ratios and Q factors at the target operating frequencies. Consider the thermal management capabilities required for the -55°C to +125°C operating range during system integration.

Part Context

This component belongs to the GC15000 series of frequency-linear tuning varactors manufactured by Microsemi, now part of Microchip Technology. The series includes models ranging from GC15001 to GC15013, offering various capacitance values to suit different tuning requirements across Ku band applications.

Replacement Considerations

Consult the factory for functional equivalents if the exact model is unavailable. Alternative package styles such as hermetic stripline-surface mount (GC15xxxx-17) or non-hermetic surface mount (GC15xxxx-450A/B) may be available upon request.
