GC15013-00

Overview

The GC15013-00 is a silicon epitaxial mesa Frequency Linear Tuning Varactor (FLTVAR) designed for wideband linear tuning in VCO and filter applications. It features a minimum breakdown voltage of 22V at 10μA leakage current, with a typical capacitance of 48pF at -4V and 10pF at -20V. The device exhibits a typical sensitivity of 0.11 and a tuning ratio of 13:1 (CJ0/CJ20). Operating temperatures range from -55°C to +125°C, with storage capabilities up to +150°C.

Feature Summary

• Frequency linear tuning characteristics enabling over one octave linear tuning without external linearization
• High Q factor and low surface noise resulting in low FM phase noise in VCO applications
• Superior passivation providing high reliability and low leakage current
• Computer-controlled grown junction epitaxy for consistent performance

Applications

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

Procurement Notes

Verify the specific package style required, as the base model number corresponds to chip-style packaging for hybrid circuits. Confirm RoHS compliance status and terminal finish details directly with the manufacturer or authorized distributor, as specifications are subject to change. Ensure ESD precautions are observed during handling due to component sensitivity.

Selection Notes

Select this component when wideband linear tuning through Ku band is required without external linearization circuits. The GC15013-00 offers a higher initial capacitance compared to lower-numbered variants in the series, making it suitable for specific frequency ranges. Evaluate the trade-off between Q factor and capacitance values to ensure compatibility with the target circuit design requirements.

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 various models differentiated primarily by their zero-bias capacitance values, ranging from approximately 0.7pF to 48pF. All models share similar structural characteristics and are designed for microwave applications.

Replacement Considerations

Direct substitutes within the same series include other GC15xxxx-00 models with different capacitance values if the circuit allows for retuning. For hermetic surface-mount requirements, consider the GC15xxxx-17 package variant. Consult the factory for non-standard package options or specific electrical parameter adjustments.
