GC1501-00

Overview

The GC1501-00 is a silicon abrupt junction tuning varactor from the GC1500 series, designed for VHF to Ku Band applications. It features a minimum breakdown voltage of 30 V at 10 uA and a maximum leakage current of 0.02 uA at 25 Volts and 25°C. The device operates within a temperature range of -55°C to +125°C. Electrical characteristics include a capacitance (CT) of 1.0 pF ±10% at -4V, a minimum quality factor of 3800 at 50 MHz, and a minimum capacitance ratio of 3.4. The thermal coefficient of capacitance is 300 ppm/°C at 4 Volts.

Feature Summary

• High Q factor and low series resistance for efficient tuning
• Abrupt junction design optimized for low phase noise
• RoHS compliant with gold plated terminations

Applications

• VHF to Ku Band tuning circuits
• Voltage Variable Filters (VVF)
• Phase shifters
• Low phase noise voltage controlled oscillators

Procurement Notes

Verify the specific package style suffix when ordering, as the base model number requires a suffix to define the mechanical configuration. Confirm that the required terminal finish matches the standard gold plating or request special finishes directly from the factory. Ensure ESD precautions are observed during handling due to component sensitivity.

Selection Notes

Select this component based on the required capacitance value and operating frequency range within the VHF to Ku Band spectrum. Consider the minimum quality factor and capacitance ratio specifications to ensure adequate performance for narrow to moderate bandwidth tuning applications. Verify that the 30 Volt breakdown rating meets the circuit's reverse bias requirements.

Part Context

The GC1501-00 belongs to the GC1500 series of 30 Volt abrupt junction tuning varactors manufactured by Microsemi (now part of Microchip Technology). This series offers a large selection of capacitance values tailored for microwave control devices. The '00' suffix indicates the chip form factor, distinguishing it from other available case styles in the product line.

Replacement Considerations

Direct substitutes within the same series include GC1500B, GC1500, GC1502, and others, which share similar electrical profiles but differ in capacitance values. When replacing, verify that the alternative part's capacitance and Q factor meet the specific circuit requirements.
