About
The Branching Filter is a high-frequency element of the antenna feed system paths, providing signal transmission in required frequency bands and signal suppression outside the operating frequency band. It provides three output paths: 27000–27002 MHz (≤0.8 dB insertion, ≥65 dB suppression at 32508 MHz), 30000–30002 MHz (≤0.9 dB insertion, ≥65 dB suppression at 32508 MHz), and 32508–32742 MHz (≤0.8 dB insertion, ≥65 dB suppression at 27000 MHz). SWR ≤1.2 between all output pairs within respective bands.
