ADCB-20-82+

Product catalog summary
Product Overview: The ADCB-20-82+ is a surface mount, bi-directional coupler designed for a frequency range of 1-800 MHz. It features a compact design with dimensions of 0.31” x 0.27” x 0.16” and is protected by US patents. This coupler is ideal for applications in cable TV and communications due to its very flat coupling and low loss characteristics.
Key Features:
  • Wide Bandwidth: Operates from 1-800 MHz, suitable for CATV and instrumentation applications.
  • Very Flat Coupling: ±0.2 dB, eliminating the need for compensation circuits.
  • Very Low Loss: 0.3 dB typical, minimizing gain reduction and temperature rise.
  • Bi-Directional: Features two coupled ports for sampling power in both directions, useful for measuring power ratios.
  • High Directivity: 16-24 dB to 400 MHz and 15-24 dB to 800 MHz, improving system performance by minimizing undesired power.
  • Excellent Return Loss: 20-40 dB to 400 MHz, reducing interaction effects with adjacent circuits.
Electrical Specifications:
  • Frequency Range: 1-800 MHz
  • Mainline Loss: 0.2-0.9 dB depending on frequency
  • Coupling: 19.5-21.8 dB across the frequency range
  • Directivity: 10-24.4 dB depending on frequency
  • Return Loss: Input and output return loss varies from 11-28 dB
  • Input Power: Up to 1.0 W from 10-800 MHz
Maximum Ratings:
  • Operating Temperature: -40°C to 85°C
  • Storage Temperature: -55°C to 100°C
Typical Performance Data: The document provides detailed performance data across various frequencies, highlighting mainline loss, coupling, directivity, and return loss. Graphs illustrate the performance trends over the frequency range.
Additional Notes: The document specifies that performance and quality attributes not expressly stated are excluded from the specification. It also mentions that the parts are subject to Mini-Circuits' standard limited warranty.
