Overview
The GC15007-150A/TR is a silicon epitaxial mesa Frequency Linear Tuning Varactor (FLTVAR) designed for wideband linear tuning in VCO and filter applications. It features a maximum leakage current of 50 nA at 20 volts, an operating temperature range from -55°C to +125°C, and a storage temperature range from -65°C to +150°C. The device provides a typical capacitance of 1.0 pF at -4V and 0.2 pF at -20V, with a sensitivity of 0.11. It achieves a typical Q value of 1000 at 4V and 50 MHz.
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 ordering suffix against official documentation to confirm package style and terminal finish. Confirm RoHS compliance status and lead times directly with Microchip Technology or authorized distributors before procurement. Ensure ESD handling precautions are strictly followed during component receipt and assembly processes.
Selection Notes
Select this varactor for Ku-band applications requiring wideband linear tuning. The GC15007-150A/TR offers a capacitance ratio of 13:1 between 0V and 20V bias. Its high Q factor supports low phase noise requirements in modulated VCO designs. Evaluate parasitic capacitance if using packaged versions for lower capacitance needs.
Part Context
This component belongs to the GC15000 series of frequency linear tuning varactors manufactured by Microsemi, now part of Microchip Technology. The series utilizes computer-controlled grown junction epitaxy to achieve consistent electrical performance across the product line.
Replacement Considerations
Consult the factory for alternative part numbers or package styles. Verify functional equivalence regarding capacitance ratios and Q values when considering substitutes within the GC15000 series.
