HHM1776B2

Balun Overview

The HHM1776B2 is a multilayer LTCC balun designed for RF applications within the 824MHz to 894MHz frequency range. It provides impedance transformation between unbalanced and balanced lines, both rated at 50 ohms. The component features a maximum insertion loss of 1.2dB and a minimum return loss of 10dB. Phase difference is specified at 180° ±10°. It utilizes a surface-mount 0603 (1608 metric) package with dimensions of 1.60mm length, 0.80mm width, and 0.60mm thickness. Operating temperature ranges from -40°C to 85°C.

Balun Feature Summary

• Utilizes low-temperature co-fired ceramic technology for compact integration
• Provides signal conversion between balanced and unbalanced transmission lines
• Designed for minimal signal attenuation in RF circuits

Balun Applications

• RF cellular communication systems
• Wireless connectivity modules
• Base station RF front-end circuits

Balun Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as standard delivery may vary by distributor channel. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the selected variant matches the required tape and reel specifications for automated placement equipment compatibility.

Balun Selection Notes

Select this component when a 50-ohm to 50-ohm impedance match is required within the 824-894MHz band. Consider the 0603 footprint constraints and the -40°C to 85°C operating range against board layout requirements. Evaluate insertion loss and phase balance specifications against system noise floor and signal integrity needs.
