F2250NLGK

Attenuators Overview

The F2250NLGK is a wideband voltage-variable RF attenuator manufactured by Renesas Electronics. It operates within a frequency range of 50 MHz to 6 GHz and features a 50 Ohm impedance. The device provides an attenuation range up to 35 dB with a typical insertion loss of 1.4 dB at 2000 MHz. It functions on a single positive supply voltage between 3.15 V and 5.25 V. Packaged in a QFN-16 surface-mount format, it supports operation from -40°C to +105°C.

Attenuators Feature Summary

• Glitch-free attenuation control mechanism ensures stable signal transitions without transient spikes during state changes.
• Wideband operational capability covering frequencies from 50 MHz to 6 GHz for versatile RF applications.
• Low insertion loss characteristic minimizes signal degradation across the operating bandwidth.

Attenuators Applications

• Wireless communication systems requiring variable gain or loss control
• RF test and measurement equipment calibration
• Base station transceiver modules

Attenuators Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm package integrity upon receipt as the QFN-16 form factor requires careful handling. Check datasheet revisions for any updates to electrical specifications or pin configurations before integration into final designs.

Attenuators Selection Notes

Select this component when a wideband, glitch-free variable attenuator is required for 50 Ohm systems. Ensure the design accommodates the 3.15 V to 5.25 V supply range and thermal requirements for the -40°C to +105°C operating temperature span. Verify that the QFN-16 footprint matches the PCB layout constraints.

Attenuators Part Context

The F2250 series represents Renesas' Glitch-Free family of voltage-controlled attenuators. These devices are designed for high-performance RF applications where signal integrity during attenuation steps is critical. The F2250NLGK specifically denotes the leaded-free, tape-and-reel or tray packaged variant suitable for automated assembly processes.

Attenuators Replacement Considerations

Consult official Renesas documentation for qualified alternatives. Cross-reference part numbers such as F2250NLGK8 for packaging variations. No direct third-party substitutes are confirmed in public sources; verify compatibility with system impedance and control voltage levels if considering other manufacturers.
