## Description

Frequency of use: 1MHZ-3GHz Loss: 0.3DB@1.5GHz Voltage resistance: DC 50V Limit current: 300MA Working principle: The broadband amplifier feeding circuit is affected by parasitic capacitance parameters at high frequency, and its performance drops rapidly. Therefore, BiasTee is needed for feeding. The BiasTee consists of ultra wideband, near ideal, high frequency inductors and capacitors without resonant points. DC blocking capacitor: DC isolation prevents DC voltage from leaking to subsequent circuit or test instrument; High frequency inductors: isolate AC information and prevent high frequency signals from leaking into the power supply system. Three ports: (one SMA-K, one SMA-J) RF port RF DC bias DC RF and DC RF+DC Application situation: A) wideband amplifier Some broadband amplifiers do not have a DC isolation capacitor inside, and the output needs to be powered. A bias device is needed. Some amplifiers integrate internal isolation capacitors without additional biasing devices. B) fiber optic communications, laser drive The drive current required for the laser diode is injected through the DC terminal of the biasing device; Communication data is injected through the RF side..
