Why the 698–2700 MHz Broadband Combiner Excels in Modern Networks
nn
The frequency range of 698–2700 MHz covers essential bands for cellular, LTE, 5G, and Wi-Fi applications. By supporting such a broad spectrum, this combiner minimizes the need for multiple filters or separate combiners, simplifying infrastructure and reducing costs. Its low VSWR (Voltage Standing Wave Ratio) of ≤1.25 ensures minimal signal reflection, which directly translates to better power transfer and reduced interference. This makes the 698–2700 MHz broadband combiner a crucial component for maintaining signal integrity in multi-operator networks.
nn
Passive Intermodulation (PIM) is a common challenge in dense RF environments, where even slight distortions can degrade performance. With a PIM rating of ≤-150 dBc (tested at 2×+43 dBm), this combiner effectively suppresses unwanted signals, preserving the clarity of your transmissions. This low-PIM characteristic is especially important in high-power applications where multiple carriers coexist, such as base stations or tower-mounted amplifiers.
