Product Detail

Product Tags

The DC port of the bias device is composed of a feeding inductor, which is used to add DC bias to prevent the AC signal of the RF port from leaking to the power supply system. Under ideal conditions, the DC terminal will not have any impact on the RF terminal signal; The RF port is composed of a blocking capacitor, which is used to input RF signals and block the DC voltage of the bias port. Through this design, a RF cable is used to transmit DC and RF signals to the remote end at the same time.

Typical applications

A) Broadband amplifier
Some broadband amplifiers have no internal DC isolation capacitor, and the output needs power supply and bias (for example, hmc460lc5 needs bias).
Some amplifiers have internal isolation capacitors, so no additional bias is required (for example, hmc462lp5 does not need bias).
B) Optical fiber communication, laser drive
The driving current required by the laser diode is injected through the DC end of the bias device;
Communication data is injected through RF terminal.
C) Optical modulator driv
D) Other test measurements, etc
