HMC8191LC4TR-R5

RF Mixers Overview

The HMC8191LC4TR-R5 is a wideband I/Q upconverter MMIC from Analog Devices Inc., designed for RF applications between 6 GHz and 26.5 GHz. It integrates mixer cells and a 90-degree hybrid within a compact 24-CLCC package measuring 3.9x3.9 mm. The device operates with an LO frequency range of 6 GHz to 26.5 GHz and provides an IF output from 0 Hz to 5 GHz. Key electrical specifications include a maximum conversion loss of 11.5 dB, a noise figure of 9 dB, an OIP3 of 24 dBm, and a P1dB compression point of 15 dBm. Power dissipation is rated at 657 mW, and it functions reliably across a temperature range of -40°C to +85°C.

RF Mixers Feature Summary

• Integrates dual mixer cells and a 90-degree hybrid for direct I/Q signal upconversion
• Supports wideband operation covering 6 GHz to 26.5 GHz RF frequencies
• Provides baseband or low-frequency IF outputs ranging from 0 Hz to 5 GHz

RF Mixers Applications

• Point-to-point microwave radio systems
• Satellite communication ground stations
• Electronic warfare and signal intelligence receivers
• Test and measurement instrumentation equipment

RF Mixers Procurement Notes

Verify the specific suffix LC4TR-R5 against official Analog Devices documentation to confirm reel packaging and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel quantity of 500 units. Cross-reference the datasheet revision date to validate current technical parameters before procurement.

RF Mixers Selection Notes

Select this component when designing systems requiring integrated I/Q upconversion without external hybrids. Consider the 24-CLCC footprint for space-constrained PCB layouts. Evaluate the 11.5 dB conversion loss and 9 dB noise figure against system link budget requirements. Confirm that the 657 mW power dissipation aligns with available thermal management solutions on the target board.

RF Mixers Part Context

This device belongs to the HMC8191 family of RF MMIC mixers. It shares functional similarities with other wideband converters but is distinct in its integrated I/Q architecture. The LC4 variant denotes the specific leadless ceramic chip carrier package type used for surface mount assembly.

RF Mixers Replacement Considerations

HMC8191LC4 and HMC8191LC4TR are functionally equivalent parts within the same series. Verify package compatibility and soldering profiles when substituting between bare die variants and reel-packaged versions.
