Delta Meccanica DCP782 is a 7/8-inch, two-slot directional coupler for DC to 3 GHz RF systems, providing adjustable sampled outputs for forward and reflected power monitoring.
Delta Meccanica DCP782 Directional Coupler is a 7/8-inch, two-slot RF monitoring component for broadcast, telecommunications and other high-power coaxial transmission systems. Covering DC to 3 GHz, it is installed in-line within a 50 Ω transmission path to provide sampled RF signals for measurement, monitoring and protection equipment. The compact coupler supports forward and reflected power measurement, making it a practical choice for transmitter output lines, combiner systems, test installations and antenna-feed networks.
The DCP782 uses directional sampling to provide a controlled low-level RF output from the main transmission line without significantly affecting the signal path. These sample outputs can be connected to RF power meters, modulation monitors, spectrum analysers, transmitter control systems or external protection equipment. Monitoring forward and reflected power helps engineers assess transmitter performance, identify mismatches and verify the condition of transmission-line and antenna systems.
Its 7/8-inch coaxial format is suited to installations using EIA 7/8-inch rigid transmission line. The two-slot arrangement provides two sampled measurement points, allowing forward and reverse power to be monitored simultaneously when connected to suitable measuring equipment. Delta Meccanica directional couplers use an adjustable probe arrangement, enabling the coupling level to be set to suit the connected monitoring device and required measurement range.
With a DC to 3 GHz operating range, Delta Meccanica DCP782 can support a wide range of RF applications, including broadcast transmitter systems and broadband communications infrastructure. High directivity assists in separating the sampled forward and reflected signals, supporting more reliable RF measurements. The 50 Ω impedance maintains compatibility with standard professional RF transmission systems and associated monitoring instruments.
Delta Meccanica DCP782 is intended for fixed RF installations where robust in-line monitoring is required. It can be used with compatible RF power meters, broadcast modulation monitors and RF dummy loads to support transmitter commissioning, routine maintenance and fault investigation.
