Description
Module parameters:Working frequency: 25k-100MHzInsertion-loss: <1dBOperating Voltage: DC1-50VNormal working current: <0.6AWeight: 15 grams
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 amplifierSome 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 driveThe 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:
