The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Mini-Circuits - Model: ZFDC-10-2-S - Condition: Used and in Excellent Condition - Price: Quote only - Availability: Not in Stock - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 1 lb, estimated - Shipping dimensions: 8X8X3 in, estimated ## Categories - Test Equipment > Electrical Test > Couplers (primary) ## Function Performs directional coupling from 10 to 1000 MHz. Samples a forward-traveling RF signal from a 50-ohm main line to a coupled port with a nominal coupling value of 10.75 dB. Provides high directivity for isolating reflected signals and handles up to 1.5W of input power. Enables signal monitoring, power measurement, or feedback loop generation with minimal mainline insertion loss. ## Platform 50-ohm coaxial RF systems operating from 10 to 1000 MHz requiring signal sampling, monitoring, or power measurement capabilities. Interfaces with RF test equipment, transmitters, amplifiers, and measurement instruments through SMA coaxial connections. Compatible with laboratory benchtop setups, production test environments, and field measurement applications where precise signal coupling ratios are needed for system characterization or feedback control loops. ## Application Directional coupler designed to operate over 10 MHz to 1 GHz frequency range with 50-ohm impedance and SMA connectors. Provides nominal coupling of approximately 10.75 dB with high directivity (up to about 35 dB), low insertion loss, and return loss suitable for RF signal sampling, monitoring, and measurement in communication test setups. Operates within power limits around 1.5 to 3 watts and temperature range from -55°C to +100°C. Interfaces through coaxial SMA connectors for integration into RF systems, enabling signal sampling without significantly disturbing the main transmission line. Commonly used in RF test instrumentation, signal routing, and antenna feed line monitoring. ## Images - - - -
