GC15006-152

Overview

The GC15006-152 is a silicon epitaxial mesa Frequency Linear Tuning Varactor (FLTVAR) designed for wideband linear tuning in VCO and filter applications. It features a non-hermetic microstrip package configuration. The device operates within a temperature range of -55°C to +125°C. Key electrical parameters include a minimum breakdown voltage of 22V at 10μA leakage, a capacitance of 140 fF at -4V reverse bias, and a typical Q factor of 1200 at 50 MHz. The sensitivity coefficient is typically 0.11.

Feature Summary

• Provides wideband linear tuning characteristics suitable for octave tuning without external linearization circuits.
• Features superior passivation for high reliability, low leakage current, and low surface noise.
• Delivers exceptional Q values compared to ion-implanted hyperabrupt diodes.

Applications

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

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and finish. Confirm RoHS compliance status with the manufacturer. Check for any product change notifications that may affect specifications or availability before finalizing procurement orders.

Selection Notes

Select this component when frequency linearity is critical for wideband tuning applications. Ensure the circuit design accommodates the non-hermetic microstrip package style. Verify that the operating temperature range meets system requirements and that the capacitance values align with the target frequency band.

Part Context

This part belongs to the GC15000 series of frequency linear tuning varactors manufactured by Microchip Technology (formerly Microsemi). The series includes various models differentiated primarily by their zero-bias capacitance values, ranging from approximately 0.7 pF to 48 pF, while maintaining consistent linearity and Q factor performance profiles.

Replacement Considerations

Direct substitutes within the same series include GC15006-00 (chip style) and GC15006-17 (hermetic stripline). Cross-manufacturer replacements require matching capacitance, Q factor, and sensitivity coefficients.
