FMBT1633

Overview

The FMBT1633 is a general-purpose broadband bias tee manufactured by Fairview Microwave. It operates within a frequency range of 50 kHz to 18 GHz and utilizes SMA connectors for both RF input and output. The component is designed to inject DC power onto an RF line while maintaining signal integrity. It features typical insertion loss of 1 dB, typical isolation of 50 dB, and a typical VSWR of 1.4:1. The unit supports a maximum DC current rating of 750 mA and a maximum DC voltage rating of 25 volts.

Feature Summary

• Broadband operation from 50 kHz to 18 GHz
• SMA connector interface for RF signal path
• High isolation between RF and DC ports
• Capable of handling up to 750 mA DC current

Applications

• RF test and measurement setups requiring DC bias injection
• Wireless communication system testing
• Component characterization and validation

Procurement Notes

Verify the specific datasheet version for the FMBT1633 to confirm mechanical dimensions and pinout configurations before integration. Ensure that the applied DC voltage does not exceed the 25-volt limit and the current remains within the 750-mA rating to prevent device damage. Cross-reference connector gender specifications with your system requirements to ensure proper mating compatibility.

Selection Notes

Select the FMBT1633 when a wide bandwidth covering microwave frequencies is required alongside moderate DC power capabilities. Compare its 50 dB isolation specification against alternatives if strict leakage prevention is critical. Consider the SMA interface standard for ease of integration into existing RF infrastructure without requiring adapter components.

Part Context

This component belongs to the category of RF misc ICs and modules, specifically functioning as a bias tee. It enables the simultaneous transmission of RF signals and DC power over a single physical connection. Such devices are essential in systems where remote biasing of active components like amplifiers or switches is necessary without disrupting the RF path.
