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: $125.00 USD - Availability: In stock, 7 available - 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 Directional coupler designed to sample or monitor RF signals within the 1 MHz to 2 GHz frequency range, providing a fixed coupling of 10 dB ±1 dB with a coupling flatness of ±1 dB and directivity of at least 15 dB. Features include low insertion loss (max 2.7 dB), VSWR max 1.70:1, and SMA female connectors for inline integration. Suited for precise power measurement, signal routing, antenna feed monitoring, and RF test applications in communication and radar systems operating at low to mid RF frequencies. Input power limited to 1 watt under good load conditions. ## Platform Directional coupler designed to sample a portion of RF power within 1 MHz to 2 GHz frequency range with 10 dB coupling and ±1 dB variation. It operates on low insertion loss of 2.7 dB max, minimum directivity of 15 dB, and maximum VSWR of 1.70:1, with 1 watt maximum input power for typical 50-ohm systems. The device uses SMA connectors for connectivity and can be integrated into RF test setups, signal monitoring, and measurement systems requiring compact low-frequency directional coupling in commercial or industrial microwave platforms. Custom connector options and configurations are available. ## Application Directional couplers are used in RF and microwave systems to sample portions of transmitted signals for measurement, monitoring, and feedback control purposes. They enable power measurement, SWR monitoring, signal injection for testing, and isolation between circuits in communication systems, radar equipment, and test instrumentation. Common applications include power amplifier monitoring, antenna system testing, signal distribution networks, and providing reference signals for automatic gain control circuits. ## Images - - - -
