Becker Mining Systems smartcom® UHF 3-Way Splitter is used to split the main arterial line into two separate Leaky Feeder Arterials. In doing so the RF power is divided equally between the two resultant arterials. The DC Power may also be routed in various directions by opening and closing the on board jumpers. DC injection screw terminals also allow this unit to be used as a make shift “Power Coupler”. Additional jumpers allow the technician to internally terminate the unused RF ports.
The RF and DC Signals present on the “Base Station” port are separated using a passive network. The 3dB SMD splitter and PCB transmission lines redirect the RF signals to the “Main Arterial” and the “Split1” ports with a minimum of loss. The DC portion is similarly split to the two ports through a set of 3 jumper terminals, one for each of the ports.
The “Main Arterial” and “Split-1” ports are driven by passive combiner networks used to re-combine the DC and RF signals. A local DC-Injection screw terminal is also included to act as a power coupler for any or all of the 3 ports simultaneously. The unit thereby takes the DC and RF signals present on the original arterial and repeats (-3dB RF + -3dB DC = max 6dB) copies on to two additional arterials.
