    The BIT-1500-385 is a bias "T" network used to supply DC power through a coaxial cable, usually to drive a remote Low Noise Amplifier or Radio Frequency system (sensor, detector, etc.) It is a 3 port (connector) device, each port carrying the following signals: (1) RF+DC, (2) DC only and (3) RF only. Port (1) is connected to the remote device, providing it with power and with a means to deliver an RF output simultaneously. Although both signals share the same coaxial cable, they are isolated from each other. Port (2) is connected to a suitable power supply to provide the necessary energy to run the remote system. Port (3) is connected to a radio device, often a receiver, which may be sensitive to the presence of DC voltages or may be shunted for ESD (Electro-Static Discharge). For these reasons, this port is void of the DC voltage (DC voltage is equal to the natural voltage present at the radio device's connector, typically 0 volt).

    A bias "T" allows you the ability to insert DC power into a coaxial cable carrying radio signals, in a controlled fashion. The insertion loss or signal penalty for enjoying this capability is low (typically 1 dB). Attempting to just "connect" DC power and the RF signal without a bias "T" results in unpredictable RF performance. It may even be harmful to the radio device you might be using (it can destroy or fatigue the gate channel of a sensitive FET amplifier often found in receiver front ends).
