This high performance 2 port Multiplexer from RFMAX expands the number of Antennas by 2 per port.

• It allows two antennas to be used on a single output.
• Used as a splitter it gives -3dB loss per output, as per theory
• It gives +3dB as a combiner with in-phase signals, as per theory
• Maintains 75% read range on both outputs.
• Inputs and outputs are matched to 50 Ohms
• Exceptionally low VSWR 1 to 1.2
• Can be used to drive two orthogonal linear antennas for cross-polarization
• The circuit filters out WIFI, Bluetooth, mobiles and other interferers above 1GHz.
