F2972NEGK8

RF Switches Overview

The F2972NEGK8 is a high-linearity broadband single-pole double-throw (SPDT) RF switch IC manufactured by Renesas Electronics. Designed for general-purpose radio frequency applications, it operates within a frequency range of 5 MHz to 10 GHz with a 50-ohm impedance. The device features a 12-VFQFPN (2x2) surface-mount package and supports supply voltages between 2.5V and 5.25V. Key electrical parameters include an insertion loss of 0.34 dB, typical off-isolation of 40 dB, input third-order intercept point (IIP3) of 77 dBm, and P1dB compression point of 40 dBm. It functions in a reflective topology across an operating temperature range from -40°C to +105°C.

RF Switches Procurement Notes

Verify current availability status directly with authorized distributors or the manufacturer, as this component may be subject to limited supply conditions or discontinuation notices. Confirm that the specific ordering suffix matches required package and tape/reel specifications. Ensure compliance with RoHS3 standards and check moisture sensitivity level classifications prior to procurement and storage handling.

RF Switches Selection Notes

Select this component when broadband operation up to 10 GHz and high linearity are required for SPDT switching tasks. Consider the 12-VFQFPN package dimensions for PCB layout constraints. Evaluate the 2.5V to 5.25V supply voltage range against system power architecture. Compare IIP3 and P1dB metrics against system dynamic range requirements to ensure adequate signal handling capabilities.

RF Switches Part Context

This part belongs to the F2972 series of SPDT reflective RF switches from Renesas Electronics. The series includes variants such as the F2976NEGK8, which offers parameter equivalence but may differ in specific isolation or loss characteristics. Evaluation boards like the F2972EVBI-75OHM are available for testing 75-ohm implementations, though the standard F2972NEGK8 is designed for 50-ohm systems.

RF Switches Replacement Considerations

The F2976NEGK8 is documented as a parameter-equivalent substitute. Verify functional compatibility regarding isolation and loss specifications before substitution. Check for any differences in package marking or manufacturing site changes indicated in product change notifications.
