Powertec RF Directional Coupler, 698 to 3800 MHz, 4.3-10 Female

The 106-PCM-DCX-6938.432 is a high-power directional coupler designed for RF systems operating from 698 MHz to 3.8 GHz. It taps off a precise fraction of the forward or reflected signal without significantly disturbing the main RF path, supporting up to 300 W of continuous power and meeting stringent third-order PIM requirements (≤ –155 dBc). With a rugged IP65-rated housing and 4.3-10 female connectors, it suits both indoor and outdoor deployments in mobile base stations, signal monitoring racks and broadcast transmission lines.

This family offers coupling levels of 5, 6, 7, 8, 10, 15 and 20 dB, each model calibrated for low insertion loss (down to 0.4 dB at the higher coupling values) and VSWR better than 1.3:1. Lower-coupling variants deliver a stronger sample for measurement equipment, while higher-coupling versions leave more power on the main link. Network engineers, test laboratories and RF integrators can select the optimal split ratio to match their monitoring sensitivity, available instrumentation and link-budget requirements.
