HHM2955A1

RF Directional Couplers Overview

The HHM2955A1 is a multilayer directional coupler manufactured by TDK Corporation, designed for signal conditioning applications within the 1.427 GHz to 5.95 GHz frequency range. This component operates with a nominal 50 Ohm impedance and features an insertion loss of 0.05 dB. It utilizes a surface-mount device (SMD/SMT) package in the 0402 (1005 metric) footprint, measuring 1.00mm in length and 0.50mm in width. The device supports board mounting and functions reliably across a temperature range of -40°C to +90°C.

RF Directional Couplers Procurement Notes

Verify that the specific order matches the HHM2955A1 part number to ensure correct frequency coverage and impedance specifications. Confirm that the required operating temperature range aligns with the component's rated limits of -40°C to +90°C. Ensure that the PCB layout accommodates the 0402 SMD package dimensions for proper soldering and electrical performance. Cross-reference the manufacturer datasheet for detailed handling and reflow profile requirements.

RF Directional Couplers Selection Notes

Select this component when a low-profile directional coupler is required for frequencies between 1.427 GHz and 5.95 GHz. The choice is driven by the need for minimal insertion loss and a small 0402 footprint. Consider the multilayer technology for robust performance in commercial grade applications. Evaluate the 50 Ohm termination compatibility with existing system architectures before finalizing the design.

RF Directional Couplers Part Context

This component belongs to the HHM series of multilayer directional couplers from TDK Corporation. The series is engineered for high-frequency signal processing tasks where size constraints are critical. The HHM2955A1 specifically addresses the demand for compact RF solutions in modern electronic devices requiring reliable signal directionality and isolation within a standard surface-mount form factor.

RF Directional Couplers Replacement Considerations

Consult official TDK documentation for verified substitute part numbers within the HHM series or equivalent product lines. Ensure any replacement maintains the same frequency range, impedance, and package dimensions.
