Overview
The SMV1763-040LF is a silicon hyperabrupt junction tuning varactor diode designed for 3 V platforms. It features an SOD-882 package with a series inductance of 0.45 nH and a maximum reverse voltage rating of 10 V. The device exhibits a typical capacitance of 6.7 pF at 0.5 V reverse bias and 2.6 pF at 2.5 V, yielding a capacitance ratio of 2.7. Operating temperatures range from -55 °C to +125 °C, with a power dissipation limit of 250 mW.
Feature Summary
- Hyperabrupt junction design optimized for low phase noise Voltage-Controlled Oscillators (VCOs) operating up to and above 10 GHz.
- High capacitance ratio achieved at low reverse voltages, suitable for low-noise and wideband UHF/VHF applications.
- Miniature SOD-882 package rated for Moisture Sensitivity Level 1 (MSL1) at 260 °C per JEDEC J-STD-020.
Applications
- Low-noise and wideband UHF and VHF Voltage-Controlled Oscillators (VCOs)
- High-volume, low-cost battery-powered tuning circuits
- Wireless systems requiring high-Q resonators
Procurement Notes
Verify the specific ordering suffix against official Skyworks documentation to confirm package type and marking. Confirm RoHS compliance status and Green™ designation prior to procurement. Ensure ESD precautions are strictly followed during handling and storage to prevent damage to the semiconductor junction.
Selection Notes
Select this component when designing for 3 V platforms requiring low series resistance and high capacitance ratios at low reverse voltages. Verify that the required operating frequency extends up to or exceeds 10 GHz and that the SOD-882 footprint aligns with the PCB layout constraints.
Part Context
The SMV1763-040LF belongs to the SMV1763 Series of hyperabrupt junction tuning varactors manufactured by Skyworks Solutions, Inc. This series includes variants such as the SMV1763-079LF, which utilizes an SC-79 package with a higher series inductance of 0.7 nH compared to the 0.45 nH found in the SOD-882 configuration.
Replacement Considerations
The SMV1763-079LF serves as a functional alternative within the same series, offering identical electrical characteristics but housed in an SC-79 package with a series inductance of 0.7 nH instead of 0.45 nH.
