Ceramic Bandpass Filter（RSN3050F200HCA）

Product Introduction:

The RSN3050F200HCA is a high-performance 3050MHz cavity bandpass filter engineered for advanced RF and wireless communication systems operating in the 2.95–3.15GHz frequency range. Featuring low insertion loss (≤2.5dB), excellent in-band ripple performance (≤1.0dB), and stable VSWR of ≤1.5:1, the filter ensures superior signal integrity and transmission efficiency in demanding applications. Its outstanding out-of-band rejection performance, reaching up to 60dB attenuation at critical interference frequencies, effectively suppresses unwanted signals and minimizes adjacent-channel interference, making it ideal for high-reliability RF front-end designs. The compact cavity structure, 50Ω impedance matching, and wide operating temperature range of -40°C to +70°C further support deployment in harsh industrial and outdoor environments.

Typical Applications

Designed for modern wireless infrastructure, the RSN3050F200HCA bandpass filter is widely used in 5G communication equipment, private LTE networks, wireless base stations, microwave communication systems, radar applications, RF testing instruments, and industrial wireless devices operating around the 3GHz spectrum. Its combination of high selectivity and strong interference suppression makes it particularly suitable for telecommunications equipment manufacturers, system integrators, and OEM RF module developers seeking to improve receiver sensitivity and overall system performance. This filter is an excellent choice for B2B customers requiring reliable RF filtering solutions for next-generation wireless connectivity and mission-critical communication systems.
