A microstrip splitter designed for the 698–2700 MHz frequency range is a compact, PCB-based RF component used to divide a single input signal into multiple outputs—typically two, three, or four—while maintaining signal integrity across a wide band. This frequency range covers key wireless communication bands, including LTE, GSM, UMTS, and Wi-Fi, making it ideal for telecom infrastructure, DAS (Distributed Antenna Systems), and RF testing environments. These splitters use microstrip transmission lines etched onto a printed circuit board to achieve signal division. This design offers several advantages: it's lightweight, cost-effective, and easy to integrate into compact systems. Despite their small size, high-quality microstrip splitters can deliver low insertion loss (as low as 0.4–0.6 dB), excellent isolation (typically 18–22 dB), and VSWR values below 1.3, ensuring efficient power transfer and minimal signal reflection. Most models are rated for 50-ohm impedance and can handle up to 50 watts of RF power, with connectors like SMA or N-type depending on the application. These devices are often housed in aluminum enclosures with IP-rated sealing for indoor or outdoor use, and they’re widely deployed in cellular base stations, signal monitoring setups, and even drone detection systems where broadband signal distribution is required.
