CG2179M2

RF Switches Overview

The CEL CG2179M2 is a single-pole double-throw (SPDT) radio frequency switch IC designed for routing RF signals. It operates within a frequency range of 50 MHz to 3 GHz and maintains a system impedance of 50 Ohms. The device utilizes pHEMT GaAs technology, offering an insertion loss of 0.45 dB and typical off-isolation of 24 dB. It functions on a supply voltage between 1.8 V and 5 V, with a specified operating temperature range from -45°C to +85°C. The component is housed in a 6-Mini Mold package.

RF Switches Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CG2179M2-C4 exist with identical core specifications but potentially different packaging or tape-and-reel configurations. Confirm RoHS compliance status and moisture sensitivity level requirements against project constraints. Ensure the selected variant matches the required 6-Mini Mold package dimensions for PCB layout compatibility. Cross-reference the manufacturer part number with distributor catalogs to confirm current availability and standard delivery periods.

RF Switches Selection Notes

Select this component for designs requiring SPDT switching functionality within the 50 MHz to 3 GHz spectrum. The low insertion loss makes it suitable for signal integrity preservation in sensitive RF paths. Consider the 1.8 V to 5 V supply range for compatibility with various logic levels. Evaluate the thermal performance within the -45°C to +85°C range for environmental suitability. Compare against other CEL RFIC switches if multiple pole configurations are needed.

RF Switches Part Context

The CG2179M2 belongs to the CEL CG2x series of RFIC switches, which are engineered for diverse wireless applications. This family provides flexible routing solutions across multiple signal paths. The series supports various configurations and package styles to integrate easily into existing electronic designs. These components are manufactured by California Eastern Laboratories, specializing in radio frequency and wireless integrated circuits.

RF Switches Replacement Considerations

Direct substitutes include the CG2179M2-C4 variant, which shares the same electrical specifications and pinout. Verify that any alternative SPDT RF switch meets the 3 GHz maximum frequency and 50 Ohm impedance requirements. Check for compatible supply voltage ranges and package dimensions to ensure mechanical interchangeability without redesigning the footprint.
