Designed for the evolving 5G landscape, these waveguide terminations handle the broad spectrum required for mid-band cellular deployment, serving as critical components at high-power antenna transition points to ensure a clean signal environment. Unlike standard coaxial loads, these versions feature precision-machined internal resistive elements made of ceramic or silicon carbide, housed in anodized aluminum or brass bodies with high-efficiency cooling fins for superior thermal management. Key features include a wide frequency range of 698-3800 MHz (covering WR-284, WR-340, and WR-430), a low VSWR of ≤ 1.10:1 to 1.20:1, and power handling options ranging from 50W to 500W. Engineered for carrier-grade performance, they offer an ultra-low PIM rating of ≤ -160 dBc to protect data throughput and are built to MIL-DTL-3922 standards with IP65/IP67 weatherproofing for reliable operation in harsh outdoor environments or high-capacity indoor head-ends. Utilizing natural convection cooling and matched 50 Ohm impedance, these rugged loads ensure nearly 100% energy absorption with a typical return loss of ≥26 dB, providing a secure and low-loss connection for permanent 5G installations.
