Isolated Switch Filter Bank
Spectrum SEI Microwave’s isolated switch filter bank offers a compact, two-channel selectable filter suitable for IF filtering. This filter bank uses integral input and output isolators to achieve the required return loss (VSWR) without compromising its narrow band performance. Spectrum’s isolated switched filter bank assembly enables RF engineers and system designers to dynamically configure their systems’ capabilities. This integrated assembly features input and output isolators to provide a consistent 50Ω load, dual selectable bandwidths (85 and 50 MHz), lightweight aluminum housing, 40 dB reverse isolation and internal voltage regulation. The filter bank measures 6.5 inches (L) × 1.75 inches (W) × 1.00 inches (H), excluding connectors, and weighs 8 ounces. The compact assembly, offering low power consumption, is designed for use in microwave receivers, downconverters and point-to-point radio systems.
