F2977NEGK

RF Switches Overview

The F2977NEGK is a high linearity broadband single-pole double-throw (SPDT) RF switch IC manufactured by Renesas Electronics. It operates within a frequency range of 30 MHz to 6 GHz with a 50-ohm impedance. Key electrical parameters include an insertion loss of 0.45 dB and typical off-isolation of 27 dB. The device functions on a supply voltage between 2.7 V and 5.25 V, consuming 80 uA of operating current. It is housed in a 12-VFQFPN package and supports an operating temperature range from -40°C to +105°C.

RF Switches Feature Summary

RF Switches Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Check for specific packaging variants such as cut tape or reel options available from distributors. Ensure the supplier provides valid traceability documentation matching the Renesas manufacturing standards.

RF Switches Selection Notes

Select this component for designs requiring low insertion loss and moderate isolation in the UHF to microwave bands. Consider the 12-VFQFPN package size for space-constrained PCB layouts. Evaluate thermal management requirements given the wide operating temperature range. Compare against alternatives if higher frequency coverage beyond 6 GHz is necessary.
