RF & DC Signal Integration for Stable and Reliable High-Frequency Bias Powering

In RF and microwave systems, many active components require not only high-frequency RF signals but also a stable DC bias supply.

RF Bias Tee combines RF signals and DC power through a common path while effectively isolating the RF and DC signals through its internal circuitry.

This allows active RF components to receive the required DC bias while simultaneously transmitting high-frequency RF signals,

improving system integration and testing efficiency.

WOKEN Technology's RF Bias Tee Series offers a variety of frequency, power, DC voltage, and current specifications to meet the requirements of

RF and microwave systems ranging from low-frequency to high-frequency applications.

RF + DC Integrated Transmission

In RF testing and communication systems, a Bias Tee is typically used to inject DC bias into an RF signal path while

preventing the DC power supply from interfering with the RF signal.

An RF Bias Tee enables:

✔ RF signal and DC power transmission through a common path
✔ DC bias injection for active RF components
✔ Isolation between the RF and DC paths
✔ Reduced system wiring and integration complexity

It is particularly suitable for RF Amplifiers, LNAs, PAs, antennas, transceiver modules, and other applications requiring external DC bias.

Key Product Advantages

Wide Frequency Range

Woken offers a variety of frequency ranges to meet different application requirements, with frequencies extending up to 70 GHz, making the series suitable for RF microwave, and high-frequency testing applications.

Low Insertion Loss

Excellent RF transmission performance minimizes the impact of the Bias Tee on the original RF signal.

This helps maintain RF signal quality and measurement accuracy.

Excellent RF / DC Isolation

One of the key functions of a Bias Tee is to provide effective isolation between the RF and DC paths.

This helps minimize interference from the DC bias supply to the RF signal.
