Overview
The SMV2202-040LF is a silicon hyperabrupt junction tuning varactor diode from the Skyworks SMV2201-SMV2205 series. It operates within a reverse voltage range of 0 to 22 V and supports a maximum forward current of 20 mA. The device features a typical capacitance of 1.355 pF at 4.0 V, with a minimum quality factor of 500 at 4.0 V and 50 MHz. Its parasitic inductance is typically 0.45 nH. Designed for surface mount applications, it utilizes an industry-standard 0402 footprint and is rated for Moisture Sensitivity Level 1 (MSL1) at 260 °C.
Feature Summary
- High Q and low series resistance for wide bandwidth, low-loss performance
- High capacitance ratio at low reverse voltages suitable for low phase noise VCOs
- Industry-standard 0402 footprints compatible with lead or lead-free soldering
Applications
- Wide bandwidth, low phase noise Voltage Controlled Oscillators (VCOs)
- Voltage-tuned phase shifters and filters in wireless systems up to 2.5 GHz
Procurement Notes
Verify component authenticity by checking the case marking DD1 against official Skyworks documentation. Confirm that the package matches the specified 0402 dimensions and ensure proper ESD handling protocols are followed during storage and assembly to prevent damage.
Selection Notes
Select this component when a specific capacitance value near 1.355 pF at 4.0 V is required. Compare its electrical specifications against other members of the SMV2201-SMV2205 series to ensure the chosen part aligns with the circuit's tuning range and impedance requirements.
Part Context
This component belongs to the SMV2201-SMV2205 series of surface mount silicon hyperabrupt tuning varactor diodes. All parts in this family share identical physical dimensions and packaging but offer varying capacitance values to accommodate different frequency tuning needs in RF designs.
Replacement Considerations
Direct substitutes within the same series include the SMV2201-040LF, SMV2203-040LF, SMV2204-040LF, and SMV2205-040LF. These alternatives maintain the same package and pinout but provide distinct capacitance ranges.
