ZFBT-352-FT+

Overview

The ZFBT-352-FT+ is a wideband coaxial bias tee from Mini-Circuits, operating from 300 MHz to 3.5 GHz. It features SMA connectors and supports high DC current up to 4A with low insertion loss of 0.5 dB typical. The device provides a feed-through terminal for the DC port and maintains good return loss. Packaged in Y460 style, it is designed for RF signal processing applications requiring simultaneous power delivery and signal transmission.

Feature Summary

• Wideband operation covering 300 MHz to 3.5 GHz
• High DC current handling capability up to 4A
• Low insertion loss of 0.5 dB typical
• Feed-through terminal design for DC port

Applications

• RF circuit biasing
• Test and measurement equipment
• Wireless communication systems

Procurement Notes

Verify the specific suffix FT+ indicates SMA connectors and RoHS compliance as documented. Confirm the Y460 package style matches your PCB or assembly requirements. Ensure the 300 MHz to 3.5 GHz frequency range aligns with your operational bandwidth needs before procurement.

Selection Notes

Select this component when a wideband bias tee is required for frequencies starting at 300 MHz. The 4A DC current rating suits applications needing substantial bias current. The SMA interface ensures compatibility with standard coaxial systems. Verify that the 0.5 dB insertion loss meets your system's signal integrity specifications.

Part Context

This part belongs to the ZFBT series of bias tees from Mini-Circuits, which are designed for RF and microwave applications. The series offers various frequency ranges and connector options. The ZFBT-352-FT+ specifically targets the 300 MHz to 3.5 GHz band with SMA interfaces.

Replacement Considerations

Check Mini-Circuits datasheets for other ZFBT models with compatible frequency ranges and connector types. Ensure any substitute supports the required 4A DC current and similar insertion loss characteristics.
