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: Pulsar Microwave - Model: C1-10-411 - Condition: Used and in Excellent Condition - Price: Quote only - Availability: 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) ## Overview Directional coupler designed for RF signal sampling and monitoring over 1 MHz to 2 GHz frequency range; provides 10 dB coupling with ±1 dB variation and flatness, insertion loss up to 2.7 dB excluding coupling loss, directivity minimum 15 dB, and VSWR up to 1.70:1; supports input power up to 1 watt with SMA female connectors standard and optional BNC, TNC, F, or N connectors; compact size 1.25" x 1.25" x 0.75"; typical applications include broadband RF signal sampling, monitoring, and testing in communication systems and measurement setups. ## Function A directional coupler that enables RF signal sampling by extracting a portion of the main signal with minimal disruption to signal flow. It provides one-way coupling between a main transmission line and a secondary port, allowing precise power measurements, signal monitoring, and feedback control. The device maintains consistent coupling ratio across its operational frequency range while ensuring low insertion loss and high directional discrimination. It features multiple ports for signal input, output, coupled output, and isolation, designed to maintain characteristic impedance throughout the signal path to minimize reflections and standing waves. ## Platform Broadband RF test and measurement systems, low power RF signal routing and monitoring setups, lab instrumentation for 1 MHz to 2 GHz frequency range; designed for integration within coaxial transmission lines using SMA connectors; supports signal coupling with 10 ±1 dB coupling factor, max 1 watt power handling; used in equipment for antenna feeding networks, receiver/transmitter signal sampling, system calibration, and RF component characterization; compact 1.25" cube outline enables embedded usage in bench-top analyzers, communication testbeds, and custom low-frequency microwave assemblies. ## Accessories A passive component featuring three SMA-Female coaxial connectors. The ports are J1 (Input), J2 (Output/Thru), and J3 (Coupled). Operation requires RF coaxial cables with mating SMA-Male connectors and a 50-ohm SMA-Male termination for any unused port to maintain proper impedance matching. This device is standalone and does not require a mainframe, backplane, or chassis. ## Images - - - -
