Z4BT-2R15G+

Overview

The Z4BT-2R15G+ is a compact Bias-Tee/Diplexer from Mini-Circuits operating from 10 to 2150 MHz. It integrates a DC bias tee and a 10 MHz diplexer into a single unit, allowing simultaneous injection of DC power, IF signals, and a 10 MHz clock reference over a single coaxial cable. The device supports a DC pass-through current of 2A at up to 48V. Designed for L-Band applications, it features low RF insertion loss and SMA connectors, making it suitable for satellite systems requiring consolidated signal and power delivery.

Feature Summary

• Integrates DC bias tee and 10 MHz diplexer in one compact package
• Enables simultaneous transmission of DC, IF, and 10 MHz reference signals
• Supports high DC pass-through capacity for powering remote units

Applications

• Powering Satellite upconverters
• Powering Low Noise Block downconverters (LNBs)
• Satellite system installations requiring single-cable signal and power injection

Procurement Notes

Verify the specific suffix 'G+' indicates RoHS compliance when ordering. Confirm connector type matches system requirements, as this model utilizes SMA interfaces. Ensure the 2A DC current limit and 48V voltage rating align with the power supply capabilities of the connected satellite equipment before integration.

Selection Notes

Select this component when space constraints require combining bias and filtering functions. It is appropriate for L-Band frequencies up to 2.15 GHz. Consider the 2A DC limit; higher current demands may require alternative models like the Z3BT series. Verify that the integrated 10 MHz diplexer meets the specific clock distribution needs of the application.

Part Context

This part belongs to Mini-Circuits' Z4BT series of all-in-one bias tees. Unlike standard bias tees, these units incorporate diplexing capabilities to separate or combine specific frequency references alongside DC and RF signals. The series is designed to simplify cabling in complex RF environments by reducing the number of required components.

Replacement Considerations

The Z3BT-2R15G+ offers similar functionality but supports higher DC current (7A) and voltage (100V). If the application requires greater power handling than the 2A/48V limit of the Z4BT-2R15G+, the Z3BT variant should be considered.
