SMV1763-079LF

Overview

The SMV1763-079LF is a silicon hyperabrupt junction varactor diode designed for 3 V platforms. It features a single configuration in an SC-79 package with a series inductance of 0.7 nH. The device supports a maximum reverse voltage of 10 V and a forward current of 20 mA, with power dissipation rated at 250 mW. Typical capacitance values range from 6.7 pF at 0.5 V to 2.6 pF at 2.5 V, yielding a capacitance ratio of 2.7. Series resistance is specified at 0.7 Ω at 900 MHz under 1 V reverse bias.

Feature Summary

• Optimized for low phase noise Voltage-Controlled Oscillators (VCOs) operating up to and above 10 GHz.
• Provides high capacitance ratio performance specifically at low reverse voltages.
• Engineered with low series resistance to support efficient tuning circuit operation.

Applications

• Low-noise and wideband UHF and VHF VCOs
• High-volume, low-cost battery-powered tuning circuits

Procurement Notes

Verify the component against official Skyworks documentation to confirm lead-free status and RoHS compliance. Ensure that the SC-79 package dimensions and polarity markings align with design requirements. Confirm operational limits regarding reverse voltage and forward current before integration into final assemblies.

Selection Notes

Select this component when designing for 3 V platforms requiring hyperabrupt junction characteristics. Evaluate the trade-off between the 0.7 nH series inductance and the required tuning bandwidth. Verify that the breakdown voltage meets the peak reverse voltage conditions expected in the target application environment.

Part Context

This part belongs to the SMV1763 series of hyperabrupt junction tuning varactors manufactured by Skyworks Solutions. The series includes variants such as the SMV1763-040LF, which utilizes an SOD-882 package with reduced series inductance. Both variants share identical electrical specifications but differ in physical footprint and parasitic inductance.
