DC 9-24V RF Bias Tee 10MHz-6GHz DC Blocker Coaxial feed LNA Module Low Noise Amplifier Broadband Frequency Amplifier for HAM radio RTL SDR LNA BiasTee Laser drive
A) Broadband amplifier
Some broadband amplifiers do not have a direct-isolating capacitor inside, and the output end needs power supply, which requires a biaser.
Some amplifiers are internally integrated with capacitors, so no additional bias is required.
B) Optical fiber communication, laser driven
The driving current required by the laser diode is injected through the DC end of the biaser
Communication data is injected through RF terminal.

Working Principle:
The broadband amplifier feed circuit has a sharp decline in performance due to the influence of parasitic capacitance parameters at high frequency, so BiasTee is required for feeding. BiasTee is composed of ultra-wideband, near-ideal, high-frequency inductance and capacitance without resonance point.
DC isolation capacitance: DC isolation to prevent DC voltage leakage to subsequent circuits or test instruments;
High-frequency inductance: isolate AC information and prevent high-frequency signal from leaking to the power supply system.
The 868M filter bandwidth is 2MHz, and the 915M filter bandwidth is 26MHz. The cut-off characteristics of these two filters are steep. It can effectively filter out out-of-band signals, reduce noise, and increase dynamic range.
