Introduction to 120Ghz Broadband Bias Tee

The BT120A 120GHz bais tee is an ultra-broadband, low loss, and supports a maximum 32dBm RF power input coaxial bias-tee, which covers the frequency of 50KHz to 120GHz, to provide a bias power supply for amplifiers, photodiodes or optical modulators, mainly used in biasing amplifiers, laser diodes, active antennas and other applications.

Frequency Range, 50KHz~120GHz

· The Voltage, 16V DC Max.

· The Current, 0.4A DC Max.

· Excellent Group Delay for All-band

· Low VSWR, 1.5:1@50KHz~120GHz Typ.

· High RF performance, ultra-competitive price

· Low Insertion loss, 3.0dB@50KHz~120GHz Max

Typical Applications

· Ultra-Broadband amplifier bias power supply

· Spatial Light Modulator bias power supply

· Photo-Communication & laser driver bias power supply
