Overview
The GC15007-127A is a silicon epitaxial mesa tuning diode 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.
Feature Summary
- Frequency Linear Tuning Varactor (FLTVAR) technology
- Wideband linear tuning capability through Ku band
- Octave tuning without external linearization
- Very low phase noise performance
Applications
- Voltage Controlled Oscillators (VCOs)
- Filters
- Modulators
- Amplifiers
Procurement Notes
Verify the specific suffix '127A' against official Microchip or Microsemi documentation to confirm package style and electrical parameters. The datasheet lists standard suffixes such as -00, -17, and -450A. Confirm availability of this exact variant with the manufacturer or authorized distributors before procurement.
Selection Notes
Select based on required capacitance at specific bias voltages and sensitivity coefficient. The GC15007-00 baseline has Cj of 1.0 pF @ -4V and sensitivity of .11. Ensure circuit design accommodates the frequency linear characteristics for octave tuning. Verify operating temperature range (-55 to +125 C) matches application needs.
Part Context
This component belongs to the GC15000 series of Frequency Linear Tuning Varactors. These devices are engineered for microwave applications requiring wideband tuning. The series includes various models differentiated by capacitance and sensitivity coefficients, all sharing similar structural and reliability features.
Replacement Considerations
Direct substitutes depend on the specific electrical parameters required by the circuit. Compare capacitance values at -4V and -20V, sensitivity coefficient, and Q factor. Other models in the GC15000 series may serve as alternatives if their specifications align with the design constraints.
