JSPHS-51+

Overview

The JSPHS-51+ is a voltage-variable analog phase shifter from Mini-Circuits, designed for surface-mount applications. It operates within a frequency range of 36 MHz to 54 MHz and provides a minimum phase shift of 180 degrees. The device features typical insertion loss of 1.2 dB with a maximum of 2.5 dB. It requires a control voltage between 0 V and 12 V and offers a typical control bandwidth of DC to 50 kHz. Typical VSWR is 1.2:1, with a maximum of 1.8:1. The component utilizes the BK276 package style, measuring 0.80 mm in length, 0.45 mm in width, and 0.25 mm in height.

Feature Summary

• Provides precise 180-degree analog phase control via variable voltage input
• Engineered for low insertion loss and stable signal integrity in RF circuits
• Utilizes rugged miniature surface-mount format for compact PCB integration

Applications

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

Procurement Notes

Verify that the specific application environment matches the 36 MHz to 54 MHz operational frequency range. Confirm that the control circuitry can supply the required 0 V to 12 V bias voltage without exceeding the specified control bandwidth limits. Ensure PCB layout adheres strictly to the provided BK276 footprint dimensions to maintain electrical performance and mechanical stability during assembly.

Selection Notes

Select this component when fixed or digitally controlled phase shifting is insufficient for the design requirements. The voltage-variable nature allows for dynamic adjustment, making it suitable for adaptive beamforming or tuning applications. Consider the low-frequency operation range compared to higher-frequency phase shifters in the Mini-Circuits portfolio to ensure compatibility with the system's carrier frequencies.

Part Context

This part belongs to Mini-Circuits' broad selection of surface-mount voltage-variable phase shifters. These components are engineered to deliver precise phase control up to 360 degrees across various frequency bands. The JSPHS-51+ specifically targets lower RF ranges, complementing other models like the JSPHS-23+ and JSPHS-42+ which cover different spectral segments.
