Overview
The SMV2201-040LF is a silicon hyperabrupt junction tuning varactor diode designed for wide bandwidth, low-loss applications. It operates at frequencies up to and above 2.5 GHz in wireless systems. The device features a high capacitance ratio at low reverse voltage, making it suitable for low phase noise Voltage Controlled Oscillators (VCOs). It utilizes an industry-standard 0402 surface mount footprint with a typical series inductance of 0.45 nH. Electrical specifications include a minimum breakdown voltage of 22 V, a maximum reverse current of 50 nA at 17.6 V, and a typical quality factor of 500 at 4.0 V and 50 MHz.
Feature Summary
- High Q and low series resistance
- High capacitance ratio at low reverse voltage
- Industry-standard 0402 footprints
Applications
- Wide bandwidth, low phase noise VCOs
- Wide range voltage-tuned phase shifters
- Voltage-tuned filters
Procurement Notes
Verify the datasheet revision number and date against official Skyworks documentation before procurement. Confirm that the component meets Moisture Sensitivity Level 1 (MSL1) requirements and adheres to JEDEC J-STD-020 standards for solder reflow temperatures. Ensure proper electrostatic discharge precautions are maintained during handling and storage to prevent device damage.
Selection Notes
Select the SMV2201-040LF when designing circuits requiring low capacitance values compared to other members of the SMV220x series. Evaluate the specific capacitance versus reverse voltage characteristics provided in the datasheet tables to ensure adequate tuning range for the target application frequency. Consider the package dimensions and PCB layout footprint constraints associated with the 0402 form factor.
Part Context
The SMV2201-040LF belongs to the SMV2201-SMV2205 series of surface mount silicon hyperabrupt tuning varactor diodes manufactured by Skyworks Solutions, Inc. These components share identical physical packages and absolute maximum ratings but differ in their nominal capacitance values. The series is engineered specifically for wide bandwidth and low-loss performance in RF and microwave applications.
Replacement Considerations
SMV2202-040LF, SMV2203-040LF, SMV2204-040LF, and SMV2205-040LF are direct replacements within the same series sharing the same package and electrical limits, though they possess different capacitance values.
