Waveguide chokes reduce leakage by 40-60dB through quarter-wave λ/4 slots (3.56mm at 21GHz) that create impedance mismatches. Field tests show they maintain <0.01% power loss in 5G mmWave systems (28/39GHz bands). Installation requires precise depth control (±0.025mm tolerance) using vector network analyzers for optimal VSWR <1.2 performance. Choke Principle Last year, ChinaSat 9B experienced a […]

Waveguide tee junctions achieve 98% power division accuracy with <0.5dB insertion loss at 18-40GHz. The E-plane (series) and H-plane (shunt) designs create unique phase characteristics – 180° shifts in E-tees vs 0° in H-tees. Precision milling maintains ±0.01mm flange alignment for VSWR <1.25 in 5G mmWave systems. Principle of T-Junction At 3 AM, alarms suddenly
