Overview
The SMV2203-040LF is a silicon hyperabrupt junction tuning varactor diode from Skyworks Solutions Inc., designed for wide bandwidth and low-loss applications. It operates at frequencies up to and above 2.5 GHz in wireless systems. The device features a single-diode configuration housed in an industry-standard 0402 (1005 metric) surface-mount package. Key electrical specifications include a minimum breakdown voltage of 22 V, a maximum reverse current of 50 nA at 17.6 V, and a typical series inductance of 0.45 nH. At 4.0 V and 50 MHz, the quality factor is guaranteed to be at least 400.
Feature Summary
- High capacitance ratio achieved at low reverse voltages
- Low series resistance supporting low phase noise performance
- Industry-standard 0402 footprint for compact integration
Applications
- Wide bandwidth, low phase noise Voltage Controlled Oscillators (VCOs)
- Voltage-tuned phase shifters
- Voltage-tuned filters
Procurement Notes
Verify component authenticity by checking the case marking DE1 against official datasheet documentation. Confirm compliance with RoHS3 standards and Moisture Sensitivity Level 1 (MSL1). Ensure storage conditions prevent moisture absorption prior to solder assembly to maintain reliability.
Selection Notes
Select this component when a specific capacitance range between approximately 0.44 pF and 1.89 pF is required across a 20 V tuning range. The SMV2203-040LF offers a balance of high Q-factor and low series inductance suitable for RF circuits operating above 2.5 GHz.
Part Context
This part belongs to the SMV2201-SMV2205 series of surface mount silicon hyperabrupt tuning varactor diodes. All members share identical physical dimensions and absolute maximum ratings but differ in their specific capacitance values and tuning characteristics.
Replacement Considerations
SMV2201-040LF, SMV2202-040LF, SMV2204-040LF, and SMV2205-040LF are direct pin-compatible alternatives within the same series offering different capacitance profiles.
