GC15007-150A

Overview

The GC15007-150A is a silicon epitaxial mesa frequency linear tuning varactor (FLTVAR) from the GC15000 series, designed for wideband linear tuning in VCO and filter applications. It features a minimum breakdown voltage of 22V at 10μA leakage current. The device provides a typical capacitance of 1.0pF at -4V reverse bias and 0.2pF at -20V reverse bias, measured at 1MHz. It exhibits a typical sensitivity of 0.11 with a tuning ratio of 13:1 (CJ0/CJ15). The component operates within a temperature range of -55°C to +125°C and maintains a typical Q factor of 1000 at 4V and 50MHz.

Feature Summary

• Frequency Linear Tuning Varactor (FLTVAR) technology providing wideband linear tuning without external linearization circuits.
• Silicon epitaxial mesa construction offering superior passivation for high reliability, low leakage current, and low surface noise.
• High Q factor performance exceeding ion-implanted hyperabrupt diodes, resulting in low FM noise in VCO applications.
• RoHS compliant manufacturing process with standard gold terminal finish.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package style and terminal finish. Confirm RoHS compliance status directly with the manufacturer or authorized distributors as specifications are subject to change. Ensure ESD precautions are observed during handling due to component sensitivity.

Selection Notes

Select this component when octave tuning over Ku band is required without external linearization. Consider the 1.0pF initial capacitance and 13:1 tuning ratio for circuit design. Evaluate the 1000 Q factor at 50MHz for phase noise requirements. Verify that the non-hermetic chip package aligns with hybrid circuit assembly capabilities.
