JSPHS-446+

Overview

The JSPHS-446+ is a voltage-variable surface-mount phase shifter manufactured by Mini-Circuits. It operates within an output frequency range of 366 MHz to 446 MHz and provides a minimum phase shift of 180 degrees. The device requires a control voltage between 0 V and 12 V, with a typical control bandwidth of DC to 50 kHz. It functions on a supply voltage of 12 V maximum and 0 V minimum. The component is housed in the BK276 case style (0.80x0.45x0.25 inches) and supports SMD/SMT installation. It is rated for operation between -40°C and +85°C.

Feature Summary

• Provides precise 180-degree voltage-controlled phase shifting capability
• Designed for surface-mount technology (SMD/SMT) integration
• Operates within a defined RF frequency band of 366 MHz to 446 MHz

Applications

• Cellular communication systems
• Radar signal processing
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the BK276 footprint matches your PCB design constraints. Ensure the control voltage requirements align with your system's power delivery capabilities. Check for any specific handling instructions regarding surface-mount assembly processes.

Selection Notes

Select this component when a narrowband phase shift solution is required specifically around the 400 MHz region. The 180-degree range suits applications needing binary phase states or quadrature generation via external networks. Consider the low insertion loss characteristics for sensitive RF chains. Verify that the 0-12V control interface is compatible with your baseband or FPGA outputs without additional level shifting.

Part Context

This part belongs to the JSPHS series of surface-mount phase shifters from Mini-Circuits. The series offers various frequency bands tailored for different wireless standards. The JSPHS-446+ specifically targets the lower end of the UHF spectrum, distinguishing it from higher-frequency variants like the JSPHS-661+ or broadband models. It shares the same physical package dimensions as other units in the BK276 family for board layout consistency.

Replacement Considerations

Direct substitutes include other JSPHS series models such as JSPHS-42+ or JSPHS-661+, provided the frequency range differences are acceptable for the application. Cross-referencing the BK276 footprint is essential for mechanical compatibility. Verify electrical parameter overlaps if substituting with non-Mini-Circuits components.
