50khz-67Ghz 1.85mm Broadband Bias Tee

The Leader-MW 50 kHz – 67 GHz Broadband Bias Tee is a precision, ultra-wideband passive component engineered to inject DC voltage or current into an active RF signal path without compromising high-frequency performance or signal integrity.

Equipped with high-frequency 1.85mm coaxial connectors on the RF ports and a dedicated DC bias port (typically SMA or solder pin), this device operates across an extensive frequency span from 50 kHz** up to 67 GHz. It features exceptionally low insertion loss, high RF-to-DC port isolation, and low VSWR throughout its operational range, preventing unwanted DC leakage into sensitive RF test equipment while suppressing RF signal degradation.

Its rugged coaxial construction provides excellent shielding, thermal stability, and minimal group delay variation, making it well-suited for demanding digital and analog applications. Typical DC handling capabilities support continuous currents up to 0.4A and voltages up to 16 V(dependent on specific model configuration).

Key Applications:
* Biasing high-speed optical modulators, photodetectors, and transceivers (PAM4, 400G/800G).
* Active RF/mmWave amplifier biasing (GaAs/GaN MMICs).
* Semiconductor characterization and high-speed pulse/digital testing.
* Wideband instrumentation, radar, and 5G/6G millimeter-wave research systems.
