GC15006-150A

Overview

The GC15006-150A is a frequency linear tuning varactor from the GC15000 series, designed for wideband linear tuning in VCO and filter applications. It features superior passivation for high reliability, low leakage current, and low surface noise. The device offers Q values well above ion-implanted hyperabrupt diodes and meets RoHS requirements per EU Directive 2002/95/EC. Standard terminal finish is gold unless otherwise specified. These silicon epitaxial mesa devices are ESD sensitive and must be handled with appropriate precautions to ensure proper functionality and longevity in microwave circuits.

Feature Summary

• Wideband linear tuning capability without external linearization
• High Q factor exceeding ion-implanted hyperabrupt diodes
• Low leakage current and low surface noise characteristics
• RoHS compliant construction with gold standard terminal finish

Applications

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

Procurement Notes

Verify the specific ordering suffix against the datasheet package options. The model provided includes a suffix that may indicate a specific package style or finish not explicitly detailed in the general series description. Confirm whether the required variant corresponds to Chip Style 00, Hermetic Stripline Surface Mount 17, or Non-Hermetic Surface Mount 450A/B. Contact the factory directly for special requirements or to confirm availability of the exact suffix configuration, as standard packages are not recommended for lower capacitance diodes due to parasitic capacitance effects.

Selection Notes

Select this component based on the required capacitance ratio and sensitivity series. The GC15006-00 variant typically exhibits a capacitance of 0.7 pF at -4V and 0.14 pF at -20V with a sensitivity of 0.11. Ensure the application circuit can accommodate the operating temperature range of -55°C to +125°C. Consider the parallel parasitic capacitance if using packaged versions, as it degrades linearity at high bias voltages. Verify that the maximum leakage current rating of 50 nA at 20 volts meets the system's noise and power consumption constraints.

Part Context

This part belongs to the Microsemi GC15000 series of Frequency Linear Tuning Varactors (FLTVAR). The series covers models GC15001 through GC15013, offering various capacitance values and tuning ratios. These devices are engineered for Ku-band applications, providing octave tuning capabilities. The series utilizes computer-controlled grown junction epitaxy to achieve consistent performance. The GC15006-150A represents a specific configuration within this lineup, tailored for precise linear tuning requirements in microwave systems.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided datasheet. Equivalent components must match the capacitance range (0.7 pF to 0.14 pF), sensitivity (0.11), and Q factor (>1200 at 50 MHz). Verify compatibility with existing PCB footprints if selecting an alternative package style. Consult the manufacturer for cross-reference recommendations to ensure electrical parameter alignment and thermal stability in the target application.
