BDCN-7-25+

Product catalog summary
Overview: This document provides the specifications for the Mini-Circuits BDCN-7-25+ bi-directional coupler, covering performance data, electrical specifications, and usage guidelines.
Specifications:
  • Frequency Range: 824 to 2525 MHz
  • Coupling: 7 dB nominal with variations across different frequency bands
  • Mainline Loss: Ranges from 0.7 dB to 1.56 dB depending on frequency
  • Directivity: Minimum of 11 dB, with typical values reaching up to 28.54 dB
  • VSWR: Typically 1.15:1 across all ports
  • Power Input: Maximum of 15W
Performance Data: The document includes graphs illustrating mainline loss, coupling, directivity, and return loss across the frequency range. Key observations include:
  • Mainline loss increases with frequency, peaking at higher frequencies.
  • Coupling and directivity show stable performance across the specified frequency range.
  • Return loss is optimized, indicating efficient signal transmission.
Design and Construction:
  • Ultra-small size and hermetically sealed design for robust performance.
  • Suggested PCB layout and land pattern provided for optimal integration.
Applications: Suitable for use in UMTS, CDMA, PCS, ISM, GPS, DCS, and TDMA systems.
