GC15006-150E/TR

Overview

The GC15006-150E/TR is a frequency linear tuning varactor from the Microsemi GC15000 series, manufactured by Microchip Technology. It is a silicon epitaxial mesa device designed for wideband linear tuning in VCO and filter applications up to Ku band. The component features a maximum leakage current of 50 nA at 20 volts and operates within a temperature range of -55°C to +125°C. Key electrical parameters include a breakdown voltage (Vb) of 22 V at 10 μA reverse current, a capacitance of 0.7 pF at -4 V bias, and a typical capacitance of 0.14 pF at -20 V bias. It exhibits a sensitivity of 0.11 and a tuning ratio (CJ0/CJ20) of 13:1, with a typical Q factor of 1200 at 4 V and 50 MHz.

Feature Summary

• Modulators
• Amplifiers

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package style and terminal finish details. Confirm RoHS compliance status and check for any factory-specific requirements regarding special packaging or handling procedures before finalizing procurement orders.

Selection Notes

Select this component when wideband linear tuning is required through Ku band frequencies. Ensure the circuit design accommodates the specified capacitance range and sensitivity profile. Verify that the operating temperature range aligns with system environmental conditions and that the package style meets board layout constraints.
