GC15001-00

Overview

The GC15001-00 is a frequency linear tuning varactor diode from the Microsemi GC15000 series, designed for wideband linear tuning in VCO and filter applications. It features a silicon epitaxial mesa structure with superior passivation for high reliability and low leakage current. The device provides an octave of linear tuning without external linearization circuits. Key electrical parameters include a minimum breakdown voltage (Vb) of 22V at IR=10μA, a capacitance of 0.7pF at -4V, and 0.2pF at -20V. It exhibits a typical sensitivity of .08 and a tuning ratio (CJ0/CJ15) of 8:1. The Q factor is typically 1400 at V=4V and 50MHz.

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct factory channels. Confirm RoHS compliance status and terminal finish specifications, as standard finishes are gold unless otherwise specified. Ensure handling procedures adhere to ESD precautions due to device sensitivity. Request current datasheets to verify any potential specification changes prior to procurement.

Selection Notes

Select the GC15001-00 for applications requiring high Q factors and low phase noise in Ku band operations. The specific capacitance values and sensitivity coefficient (.08) define its tuning range and linearity. Consider package options such as chip style for hybrid circuits or hermetic stripline packages based on integration requirements. Consult the factory for alternative capacitance values if standard parameters do not meet circuit needs.

Part Context

The GC15001-00 belongs to the GC15000 series of frequency linear tuning varactors manufactured by Microsemi, now part of Microchip Technology. This series is engineered for microwave products utilizing computer-controlled grown junction epitaxy. The devices are optimized for functional performance through the Ku band, offering consistent sensitivity and high modulation rate capabilities for modulated VCO applications.

Replacement Considerations

Direct substitutes within the same series include models with similar capacitance and Q characteristics, such as GC15002-00 or GC15003-00, depending on specific capacitance requirements. Verify pin compatibility and package style before substitution. Consult the manufacturer for cross-reference data regarding alternative packaging styles like the 450A non-hermetic surface mount option.
