Overview
The SMV2204-040LF is a silicon hyperabrupt junction tuning varactor diode from Skyworks Solutions, 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 minimum breakdown voltage of 22 V and a maximum reverse current of 50 nA at 17.6 V. Electrical specifications include a typical series inductance (LS) of 0.45 nH and a typical parasitic capacitance (CP) of 0.075 pF. At 4.0 V, the capacitance ranges from 2.86 pF to 3.95 pF, while at 20.0 V, it ranges from 0.61 pF to 1.02 pF. The component is housed in an industry-standard 0402 surface mount package.
Feature Summary
- High quality factor and low series resistance for minimal signal loss
- High capacitance ratio achieved at low reverse voltages
- Compatible with standard 0402 footprints for compact designs
- Rated for Moisture Sensitivity Level 1 at 260 °C
Applications
- Wide bandwidth, low phase noise Voltage Controlled Oscillators (VCOs)
- Voltage-tuned phase shifters
- Voltage-tuned filters
Procurement Notes
Verify the specific part number against official Skyworks documentation to ensure accuracy. Confirm that the ordering suffix matches the required tape and reel format. Check for any recent product discontinuation notifications or lifecycle status updates directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a high capacitance ratio at low reverse voltages is required for low phase noise performance. Ensure the operating frequency aligns with the specified range up to and above 2.5 GHz. Verify that the 0402 footprint constraints fit the PCB layout requirements and that the thermal characteristics meet the application's soldering conditions.
Part Context
This component belongs to the SMV2201-SMV2205 series of surface mount hyperabrupt tuning varactor diodes. All members of this series share identical physical dimensions and package types but differ in their specific capacitance values and tuning characteristics to suit various circuit requirements within the same form factor.
Replacement Considerations
Other members of the SMV2201-SMV2205 series offer different capacitance profiles but maintain the same 0402 footprint. Cross-referencing datasheets is necessary to confirm if alternative series members provide the required electrical parameters for the specific design.
