Overview
The SMV1265-011LF is a hyperabrupt junction tuning varactor diode manufactured by Skyworks Solutions, Inc. It is housed in an SOD-323 surface-mount package with a series inductance of 1.7 nH. The device operates within a temperature range of -55°C to +125°C and features a reverse breakdown voltage of 28 V. Electrical specifications include a typical capacitance of 12.5 pF at 1 V and 0.58 pF at 26 V (measured at 1 MHz). The component exhibits a typical capacitance ratio of 19.5 and a series resistance of 2.4 Ω at 470 MHz.
Feature Summary
- High capacitance tuning ratio suitable for wideband applications
- Low series resistance design
- Hyperabrupt junction construction
Applications
- Wideband RF and microwave Voltage Controlled Oscillators (VCOs)
- Analog phase shifters
- Digital TV tuners
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the package type and marking code. Confirm compliance with RoHS standards and lead-free requirements before procurement. Ensure ESD precautions are observed during handling and storage to prevent damage to the semiconductor junction.
Selection Notes
Select this component when high capacitance tuning ratios are required for wideband frequency synthesis. Compare the SOD-323 package variant against the SOD-882 option based on available board space and parasitic inductance constraints. Verify that the operating voltage range aligns with the circuit's biasing requirements.
Part Context
This part belongs to the SMV1265 series of hyperabrupt junction tuning varactors designed for high-volume commercial applications. The series includes variants such as the SMV1265-040LF, which utilizes a different package footprint. These devices are engineered to provide low series resistance alongside high tuning ratios for efficient RF signal processing.
Replacement Considerations
The SMV1265-040LF serves as a direct functional alternative within the same series, distinguished primarily by its SOD-882 packaging and lower series inductance.
