LTC5548IUDB#TRMPBF

RF Mixers Overview

The LTC5548IUDB#TRMPBF is a high-performance microwave double-balanced passive mixer manufactured by Analog Devices Inc. It operates within a radio frequency range of 2 GHz to 14 GHz and supports a wideband intermediate frequency from DC to 6 GHz. The device features a maximum conversion loss of 7.1 dB and a noise figure of 8 dB. Key linearity metrics include an output third-order intercept point (OIP3) of 17.3 dBm and a P1dB compression point of 15.2 dBm. It functions on a 3.3 V supply with a current draw of 120 mA, operating reliably between -40°C and +105°C in a compact 12-lead QFN package.

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm RoHS compliance and lead-free specifications prior to integration. Validate the specific suffix configuration against schematic requirements to ensure correct packaging and tape-and-reel handling parameters match manufacturing processes.

RF Mixers Selection Notes

Select this component when broad RF bandwidth up to 14 GHz is required alongside a DC-coupled IF path. Evaluate thermal management capabilities as the device operates at elevated temperatures up to 105°C. Compare linearity specifications against system dynamic range requirements to ensure adequate performance margins for complex modulation schemes.
