 Recently, Techigh circuit has manufactured one 5g used antenna combiner PCB for a famous antenna enterprise. The PCB is made of domestic high-frequency PTFE material – Zhongying tech ZYF220D. It required PIM (Passive Intermodulation) test. The frequency requirement is 703-798 / 885-960MHZ, and the intermodulation value is required less than - 115dbm. It is finished whole processes within our company, also the PIM is tested by our own instrument and qualified.

  Antenna combiner is a kind of circuit or device that allows two transmitters to share an antenna without adverse effects on each other. Combiner is generally used in the transmitting end of antenna. The function is to combine two or more RF signals from different transmitters into one and send them to the RF device of antenna transmitting. At the same time, it can avoid the interactions among the signals of each port.

 The antenna combiner is widely used in 4G and 5g base station RF front-end units. With the construction of national 5g new infrastructure, the market is huge and the relevant high frequency boards are highly needed.
