Waveguide dividers in satellites ensure precise signal distribution (0.1dB imbalance) across multiple transponders, handling high power (50W+) at Ka/Q bands (26-40GHz). Their low insertion loss

Waveguide variable attenuators provide precise RF power control (0-30dB range) with low insertion loss (<0.5dB). They handle high power (up to 100W) and frequencies (18-40GHz),

Waveguide pressure windows typically withstand 50-100 psi differential pressure when constructed with 0.060″ thick alumina ceramic (Al₂O₃) for X-band (8-12 GHz) applications, exhibiting less than

The thickness of waveguide shims depends on the required frequency adjustment and flange type, typically ranging from 0.001″ to 0.020″ (0.025-0.5mm) for standard WR-90 waveguides.

When calculating waveguide twist specifications, engineers must account for the operating frequency range (e.g., 18-26.5 GHz for K-band WR-42 waveguide) and required polarization rotation (typically

When selecting waveguide detector diodes, focus on matching the diode’s frequency range to your waveguide band (e.g., 26.5-40 GHz for Ka-band WR-28 systems), ensuring sensitivity

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

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.
