LTC5548IUDB

RF Mixers Overview

The LTC5548IUDB#TRMPBF is a high-performance microwave double-balanced passive mixer from Analog Devices Inc., designed for frequency upconversion or downconversion. It operates within a radio frequency range of 2 GHz to 14 GHz, with a local oscillator frequency spanning 1 GHz to 12 GHz and a wideband DC to 6 GHz intermediate frequency output. Key electrical parameters include a maximum conversion loss of 7.1 dB, a noise figure of 8 dB, an OIP3 of 17.3 dBm, and a P1dB compression point of 15.2 dBm. The device requires a 3.3 V supply voltage and draws 120 mA of operating current. It is housed in a compact 12-lead QFN package (QFN-12) suitable for surface mount installation.

RF Mixers Feature Summary

• High-performance microwave double-balanced passive architecture
• Wideband intermediate frequency capability extending to DC
• Supports both frequency upconversion and downconversion operations

RF Mixers Applications

• Radar systems
• Microwave communication links
• Frequency translation circuits

RF Mixers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix (e.g., TRMPBF vs TRPBF) matches the required packaging format. Check RoHS compliance status and lead-free specifications against current regulatory requirements. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

RF Mixers Selection Notes

Select this component when designing systems requiring operation above 2 GHz with low conversion loss. Consider the 120 mA supply current and 3.3 V requirement for power budgeting. Evaluate the 17.3 dBm OIP3 for linearity needs in dense signal environments. Ensure the QFN-12 footprint fits the PCB layout constraints.

RF Mixers Part Context

This part belongs to the LTC5548 series of RF mixers. It shares functional similarities with the LTC5549 but differs in specific performance metrics such as noise figure and supply current. The device is distinct from active mixers, relying on passive switching elements for signal processing.
