Mini-Circuits ADC-6-10-75+ is a high-performance surface-mount (SMD) directional coupler developed by Mini-Circuits, designed for RF signal processing applications within the 20 MHz to 1000 MHz frequency range. This device features a 75Ω impedance match and is specifically optimized for use in cable television (CATV), broadband communication systems, and RF test equipment. It offers low insertion loss, high directivity, and excellent coupling flatness across the operating bandwidth.

　　Key Performance Parameters (Typical Values under Standard Test Conditions):

　　- Coupling: 6.6 dB ± 0.5 dB, over 20–1000 MHz

　　- Insertion Loss: 2.1 dB maximum from 20 to 1000 MHz

　　- Directivity: 15 dB minimum, 20–1000 MHz

　　- Input VSWR: ≤1.3 at 350 MHz

　　- Maximum Input Power: 0.5 W

　　Frequency-Band Performance Characteristics (Typical Values):

　　- Low Band (20–200 MHz): Coupling = 6.6 dB, Directivity = 15.8 dB

　　- Mid Band (200–500 MHz): Coupling = 6.7 dB, Directivity = 15.7 dB

　　- High Band (500–1000 MHz): Coupling = 6.7 dB, Directivity = 13.8 dB
