F2255NLGK8

Attenuators Overview

The F2255NLGK8 is a wideband voltage variable RF attenuator (VVA) manufactured by Renesas Electronics Corporation. It operates within a frequency range of 1 MHz to 3 GHz and provides a maximum attenuation of 34.6 dB with a typical insertion loss of 1.1 dB. The device features a 50 Ohm impedance and is housed in a 16-VFQFN package with an exposed pad. This component is designed for precise signal amplitude control in wireless and RF applications.

Attenuators Feature Summary

• Provides precise voltage-controlled attenuation tuning across a wide bandwidth
• Features low insertion loss to minimize signal power degradation during transmission
• Utilizes a compact surface-mount package design suitable for high-density PCB integration

Attenuators Applications

• Wireless communication systems requiring dynamic signal level adjustment
• RF front-end modules for mobile devices and base stations
• Test and measurement equipment needing accurate signal attenuation

Attenuators Procurement Notes

Verify the specific suffix 'K8' against the manufacturer's official datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure that the 16-VFQFN exposed pad thermal requirements are met in the PCB layout design. Cross-reference the part number with current Renesas Electronics distribution channels to confirm availability status and lead times prior to finalizing procurement orders.

Attenuators Selection Notes

Select this component when a wide frequency range up to 3 GHz is required alongside precise voltage-variable attenuation control. The choice is driven by the need for low insertion loss and compact form factor in space-constrained RF designs. Evaluate the 50 Ohm impedance match against system requirements to ensure minimal signal reflection and optimal power transfer efficiency throughout the operating band.

Attenuators Part Context

The F2255 belongs to Renesas Electronics' portfolio of voltage variable RF attenuators, originally developed under Integrated Device Technology (IDT). These components are engineered for high-performance wireless connectivity solutions. The F2255NLGK8 variant specifically addresses the demand for wideband signal management in modern RF architectures, offering reliable performance in consumer electronics and infrastructure applications.

Attenuators Replacement Considerations

Consult the official Renesas Electronics replacement guide or cross-reference tools for verified substitute part numbers. Do not assume functional equivalence based on generic specifications alone. Verify that any alternative component matches the exact frequency range, attenuation characteristics, and package dimensions before implementation.
