Overview
The GC15006-127A is a silicon epitaxial mesa Frequency Linear Tuning Varactor (FLTVAR) from the GC15000 series. It provides wideband linear tuning for VCO and filter applications through Ku band. Key electrical parameters include a minimum breakdown voltage of 22V at 10μA leakage, a capacitance of 0.7pF at -4V bias, and a typical sensitivity of 0.11. The device achieves a typical Q factor of 1200 at 50MHz and supports a tuning ratio of 13:1.
Feature Summary
- Frequency linear tuning characteristics enable over one octave of linear tuning without external linearization circuits.
- Superior passivation ensures high reliability, low leakage current, and low surface noise performance.
- High Q values exceed those of ion-implanted hyperabrupt diodes, resulting in low FM noise in VCO applications.
Applications
- Voltage Controlled Oscillators (VCOs)
- Filters
- Modulators
- Amplifiers
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package style and terminal finish. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors. Ensure ESD handling precautions are strictly followed during storage and assembly processes.
Selection Notes
Select this component based on required capacitance values at specific bias voltages and target Q factors. Evaluate the sensitivity parameter to ensure compatibility with circuit linearity requirements. Consider operating temperature ranges and maximum leakage current limits for the intended application environment.
Part Context
This part belongs to the GC15000 series of frequency linear tuning varactors manufactured by Microchip Technology. The series utilizes computer-controlled grown junction epitaxy to achieve consistent performance across models. These devices are designed for microwave applications requiring precise frequency control.
Replacement Considerations
Direct substitutes within the GC15000 series include GC15001-00 through GC15013-00, which share similar packaging and functional characteristics but differ in capacitance and Q values. Verify electrical specifications match before substitution.
