Working principle
Broadband amplifier feeding circuit, high frequency is affected by parasitic capacitance parameters, and its performance drops sharply, so BiasTee is required for feeding.
BiasTee is composed of ultra-wideband, near-idealized, high-frequency inductors and capacitors with no resonance point.
DC blocking capacitor:blocking DC to prevent DC voltage from leaking to subsequent circuits or test instruments;
High-frequency inductance:Isolate AC information to prevent high-frequency signals from leaking to the power supply system.
Application range
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, so no additional biasers are needed.
Optical fiber communication, laser drive
The driving current required by the laser diode is injected through the DC terminal of the biaser;
Communication data is injected through the RF terminal.
Other test and measurement applications
Package included
1 x RF DC Block
