Waveguide combiners reduce interference through ​​precise impedance matching​​ (VSWR <1.25:1) and ​​isolated port designs​​ that provide >30dB isolation between channels. They utilize ​​ferrite circulators​​ to direct signals unidirectionally with <0.3dB insertion loss while suppressing reflected waves by >20dB. The ​​tuned resonant cavities​​ maintain phase coherence (±5° tolerance) across operating bands (e.g., 3.7-4.2GHz for C-band), and […]

A waveguide isolator blocks reflections using ​​ferrite material​​ (e.g., YIG garnet) biased by ​​permanent magnets​​ (typically 0.1-0.3 Tesla) to create ​​non-reciprocal Faraday rotation​​ (45°±2° at 18GHz). The ​​forward wave​​ passes with <0.5dB insertion loss, while ​​reflected waves​​ are attenuated by >20dB through absorption in resistive cards. The isolator’s ​​VSWR​​ is maintained below 1.15:1 across its
