HMD1713A-20M3500

RF Directional Couplers Overview

The HMD1713A-20M3500 is a general-purpose RF directional coupler manufactured by Soshin Electric Co., Ltd. It operates within a frequency range of 3200 MHz to 4000 MHz (3.2 GHz to 4 GHz). The component features a nominal coupling factor of 20.0 ± 1.0 dB, with a typical value of 20.03 dB. It utilizes a surface-mount device (SMD) package without leads, specifically a 5-SMD configuration. The physical dimensions are 5.08 mm in length, 3.18 mm in width, and 1.05 mm in height. The device is compliant with RoHS3 standards.

RF Directional Couplers Feature Summary

• Provides precise signal sampling via a 20 dB coupling factor for monitoring applications
• Designed for high-frequency operation between 3.2 GHz and 4 GHz
• Utilizes a compact leaded-free surface mount package for automated assembly

RF Directional Couplers Applications

• RF signal monitoring in wireless communication systems
• Power measurement in radio frequency test equipment
• Signal injection in base station architectures

RF Directional Couplers Procurement Notes

Verify the specific suffix 'M3500' against the manufacturer's official datasheet to confirm the exact frequency band and tolerance specifications. Ensure that the procurement channel provides documentation confirming RoHS3 compliance status. Cross-reference the 5-SMD no-lead package dimensions with your PCB footprint library to guarantee mechanical fitment before placing orders.

RF Directional Couplers Selection Notes

Select this component when a fixed 20 dB coupling ratio is required for the 3.2–4 GHz spectrum. Consider the 5.08 x 3.18 mm form factor for space-constrained layouts. Evaluate insertion loss and directivity parameters if system sensitivity demands stricter performance than the standard general-purpose classification allows.
