About
The Branching Filter serves the critical purpose of ensuring precise signal transmission and suppression within an antenna feed system. It allows for the passage of signals in required frequency bands while effectively attenuating unwanted signals outside of these operational ranges. This component is an essential part of the high-frequency (HF) path within antenna systems, likely for spacecraft applications given the context of the website. Key performance parameters include specific SWR (Standing Wave Ratio) values across different frequency bands (27000-27002 MHz, 30000-30002 MHz, 32508-32742 MHz) and decay (attenuation) characteristics, both within and outside the operational bands. For instance, it boasts a decay of not less than 65 dB in certain frequency ranges, indicating strong signal suppression capabilities.
