Bias Tee Wideband 10MHz-3GHz for HAM radio RTL SDR LNA Low Noise Amplifier 50VDC.

Description: 

Features:  

Frequency of use: 10MHZ-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. 

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.
