{"product_id":"rfi-sp6938-53a4-43","title":"RFI SP6938-53A4-4.3 Wideband 4-Way Low PIM Wilkinson Splitter\/Combiner, 698-3800 MHz, 4.3-10 Female","description":"Feeding four antennas from one source sounds simple until a fault on one branch drags the others down with it. A Wilkinson splitter is the engineered answer: it divides power 4 ways with real isolation between the outputs, so each branch stays independent. The SP6938-53A4-4.3 is RFI's second-generation wideband design, covering 698–3800 MHz — every Australian cellular band from 700 MHz through mid-band 5G — on low-PIM 4.3-10 female interfaces.\n\n\u003ch2\u003eProduct Features:\u003c\/h2\u003e\n\n\u003cul class=\"custom-list-tick\"\u003e\n \u003cli\u003e4-way Wilkinson topology — isolated outputs, not a passive tee that couples every fault to every branch.\u003c\/li\u003e\n \u003cli\u003eFull 698–3800 MHz span: 700, 850\/900, 1800, 2100, 2300, 2600 and 3500 MHz in one component.\u003c\/li\u003e\n \u003cli\u003eLow-PIM construction — the requirement for any path a carrier will connect to.\u003c\/li\u003e\n \u003cli\u003e4.3-10 female interfaces, the current DAS and carrier standard.\u003c\/li\u003e\n \u003cli\u003eSecond-generation design; also available in other port counts across the series.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplication Areas:\u003c\/h2\u003e\n\n\u003cul class=\"custom-list-tick\"\u003e\n \u003cli\u003eDistributing signal to multiple DAS antennas from one head end.\u003c\/li\u003e\n \u003cli\u003eCombining or splitting between sectors on shared cellular infrastructure.\u003c\/li\u003e\n \u003cli\u003eMulti-antenna in-building and tunnel coverage systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSelection \u0026amp; Installation Notes:\u003c\/h2\u003e\n\n\u003cul class=\"custom-list-tick\"\u003e\n \u003cli\u003eEvery port must see 50 Ω.
