LTC5576IUF#PBF

RF Mixers Overview

The LTC5576IUF#PBF is a high linearity active upconverter mixer manufactured by Analog Devices Inc. It operates within an RF frequency range of 3 GHz to 8 GHz, utilizing a local oscillator (LO) input spanning the same 3 GHz to 8 GHz band. The device features a noise figure of 17.5 dB and provides a gain of -0.6 dB. It requires a supply voltage between 3.1 V and 5.3 V with a typical current consumption of 105 mA. Packaged in a 16-lead QFN (4x4 mm) surface-mount format, it supports operation across a temperature range from -40°C to +85°C.

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Request official datasheets and test reports to confirm electrical parameters match specifications. Inspect packaging integrity upon receipt. Ensure ESD-safe handling procedures are followed during storage and assembly. Cross-reference ordering part numbers carefully to avoid variant mismatches.

RF Mixers Selection Notes

Select this component when designing upconversion stages requiring wide bandwidth coverage from 3 GHz to 8 GHz. Consider its low LO leakage and high linearity for applications sensitive to intermodulation distortion. Evaluate power supply requirements against the specified 3.1 V to 5.3 V range and 105 mA current draw. Assess thermal management needs given the QFN package constraints and operational temperature limits.
