C-Band Notch Filter for 5G n77/n78 & Satellite Coexistence | 3700-3980MHz, 40dB

Concept model CNF03700M03980Q10A is a high-performance C-Band cavity notch filter engineered to suppress interference across the 3700-3980 MHz frequency range—a critical band for 5G NR n77/n78 deployments and satellite C-band uplinks. Featuring ≥40dB rejection and low insertion loss (≤2.0dB) across wide passbands (DC-3600MHz & 4080-7000MHz), this filter is essential for enabling clean spectrum sharing, protecting sensitive receivers, and ensuring compliance in dense RF environments.

Descripton

Notch filter known also as a band stop filter or band stop filter, blocks and rejects frequencies that lie between its two cut-off frequency points passes all those frequencies either side of this range. It is another type of frequency selective circuit that functions in exactly the opposite way to the Band Pass Filter we looked at before. Band-stop filter can be represented as a combination of low-pass and high-pass filters if the bandwidth is wide enough that the two filters do not interact too much.

Applications

• 5G NR Infrastructure

• Satellite Communication (SATCOM)

• Fixed Wireless Access (FWA)
