CG2176X3

RF Switches Overview

The CG2176X3 is a pHEMT GaAs MMIC SPDT RF switch designed for high-power applications in WiMAX and WiFi systems. It operates within a frequency range of 2.3GHz to 5.85GHz, supporting 802.11a/b/g/n/ac standards. The device features a 50-ohm impedance and functions with a supply voltage between 1.8V and 5V. Packaged in a compact 6-TSON (XFDFN) format with exposed pads, it ensures reliable performance across an operating temperature range of -45°C to 85°C.

• 802.11a/b/g/n/ac compliant wireless devices
• RF signal routing in multi-band transceivers

RF Switches Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CG2176X3-C2 exist with identical core specifications but potentially different packaging or reel configurations. Confirm that the required evaluation board, CG2176X3-EVAL, includes necessary DC blocking capacitors for all RF ports during testing phases. Ensure compliance with RoHS3 and REACH regulations for intended market deployment. Check moisture sensitivity level classifications for proper handling and storage conditions prior to assembly.

RF Switches Selection Notes

Select this component for designs requiring a robust SPDT switch capable of handling high power levels within the 2.3GHz to 5.85GHz spectrum. The 6-TSON package offers a small footprint suitable for space-constrained mobile and base station applications. Consider the 1.8V to 5V supply range for compatibility with various logic levels. Evaluate thermal management needs given the -45°C to 85°C operating window and the exposed pad design for heat dissipation.

RF Switches Part Context

Part of the CG2176 series from CEL, focusing on GaAs MMIC solutions for wireless communications. The X3 variant specifically denotes the 6-pin thin SSON package style. It serves as a critical passive/active hybrid element in RF front-end modules, enabling signal path selection between antennas and transceivers without significant insertion loss or distortion in modern broadband networks.

RF Switches Replacement Considerations

CG2176X3-C2 is a confirmed substitute part number offering equivalent electrical characteristics and functionality. Verify package marking differences if visual inspection is required for inventory management. No other cross-model substitutes are documented in public sources; direct replacement should be limited to verified suffix variations.
