Description:

Frequency of use: 10MHZ-6GHz

■Loss: 0.5dB@3GHz 1.2dB@6GHz

■Supply voltage: 9-24V

Applications:

A) Broadband Amplifier

Some broadband amplifiers do not have a DC blocking capacitor inside, and the output terminal needs to be powered and a biaser is required.

Some amplifiers have built-in blocking capacitors, which do not require additional biasers.

B) Optical fiber communication, laser driver

The driving current required by the laser diode is injected through the DC terminal of the biaser;

Communication data is injected through the RF side.

working principle

Wideband amplifier feeding circuit, high frequency is affected by parasitic capacitance parameters, and the performance drops sharply, so BiasTee needs to be used for feeding. BiasTee consists of ultra-broadband, near-idealized, high-frequency inductors and capacitors without resonance points.

DC blocking capacitor: block DC to prevent DC voltage from leaking to subsequent circuits or testing instruments;

High-frequency inductor: isolates AC information and prevents high-frequency signals from leaking into the power supply system.
