Overview
The GC15009-00 is a silicon epitaxial mesa Frequency Linear Tuning Varactor (FLTVAR) designed for wideband linear tuning in VCO and filter applications. It features a peak reverse voltage of 22V, a capacitance of 5.0pF at -4V bias, and 0.9pF at -20V bias. The device offers a typical sensitivity of 0.11 and a tuning ratio (CJ0/CJ20) of 13:1. It maintains a Q value of 800 at 4V and 50MHz. Operating temperature ranges from -55°C to +125°C.
Feature Summary
- Frequency linear tuning characteristics enable over one octave linear tuning without external linearization.
- High Q factor and low surface noise contribute to low FM phase noise in VCO applications.
- Superior passivation ensures high reliability and low leakage current.
- Computer-controlled grown junction epitaxy provides consistent performance.
Applications
- Voltage Controlled Oscillators (VCOs)
- Filters
- Modulators
- Amplifiers
Procurement Notes
Verify the specific datasheet revision and package style with the manufacturer before ordering. Confirm RoHS compliance status and terminal finish requirements. Check for any Product Change Notifications that may affect specifications or availability. Ensure ESD handling precautions are followed during storage and assembly.
Selection Notes
Select this component based on required capacitance values at specific bias voltages and the necessary Q factor for the target frequency range. Consider the sensitivity parameter for modulation linearity requirements. Verify that the operating temperature range meets the application environment constraints.
