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

To accurately measure waveguide flange sizes, use ​​precision calipers​​ (resolution 0.01mm) to verify ​​flange outer diameter​​ (WR-90 standard: 58.17±0.05mm) and ​​bolt circle diameter​​ (47.55±0.03mm for UG-39/U). Check ​​flatness​​ with optical flats (<0.02mm deviation across surface) and measure ​​groove depth​​ (3.18±0.05mm for choke flanges) with depth micrometers. For ​​alignment​​, use go/no-go gauges to test pin-slot tolerance

To test waveguide connector performance, measure ​​insertion loss​​ (should be <0.1 dB for Ka-band) and ​​VSWR​​ (target <1.25:1) using a vector network analyzer. Conduct ​​durability tests​​ (500+ mating cycles) while monitoring ​​contact resistance​​ (must stay below 5mΩ). Verify ​​EMI shielding​​ effectiveness (>90dB attenuation at 40GHz) and ​​thermal stability​​ (-55°C to +125°C operating range). For millimeter-wave

Waveguide flanges are critical for connecting RF/microwave systems, with four primary types dominating 90% of industrial use: ​​UPC flanges​​ (WR-90 standard, 8.2–12.4 GHz, 0.1dB insertion loss) are universal for lab equipment; ​​CPR flanges​​ feature choke grooves for military radars, achieving -80dB leakage; ​​cover flanges​​ enable quick testing with precision 2µm surface finishes; and ​​square flanges​​

A waveguide dummy load absorbs RF/microwave energy (e.g., 1–40 GHz) to test transmitters safely, preventing signal reflection. Typical models handle 50W–50kW power with VSWR <1.1. Used in radar calibration (e.g., 90% of military systems) and 5G base station testing, featuring water-cooled designs for sustained 30-minute 100% duty cycles.

Silver-plated EPDM (0.03–0.1mm thickness) dominates for 18–110 GHz systems, offering <0.05 dB insertion loss and 80°C thermal stability. Conductive fluoroelastomers (MIL-G-83528B) handle 40+ dB shielding in military radars. Install with 7–12 N·m torque on WR-90 flanges; replace every 5,000 operational hours in high-vibration environments. Material Requirements Last year, during the vacuum thermal cycling test of

Use waveguide flange covers during transport/storage (preventing 0.1–5 dB insertion loss from dust) or inactive system periods. Essential in corrosive environments (e.g., coastal 5G sites), they block moisture ingress per MIL-STD-348A. Install with torque-controlled bolts (12–15 N·m for WR-90) and replace every 6–12 months in high-humidity areas. Protection Requirements Last June, the AsiaStar 9 satellite

Waveguide flange specifications ensure ​​<0.1dB insertion loss​​ by maintaining ​​sub-0.05mm alignment tolerances​​ (per MIL-STD-392). Standardized flanges (e.g., ​​WR-90 UG-387/U​​) prevent RF leakage with ​​>60dB shielding​​, while ​​gold-plated contacts​​ and ​​torque limits (8-12 in-lb)​​ guarantee ​​VSWR <1.15​​ up to ​​40GHz​​ in radar/satellite systems.
