MD-149-PIN

RF Mixers Overview

The MD-149-PIN is a double-balanced mixer manufactured by MACOM Technology Solutions, designed for radio frequency applications spanning 10 MHz to 1.5 GHz. It utilizes a medium barrier Schottky diode ring quad connected via transformers to ensure balanced line operation. The component features a fully hermetic FP-2 package and nominal 50 Ohm impedance. Key electrical specifications include a typical midband conversion loss of 6 dB and LO-RF isolation of 40 dB. Maximum input power is rated at 300 mW, with a maximum IF port current of 50 mA.

RF Mixers Feature Summary

• Double-balanced architecture using a Schottky diode ring quad for enhanced port isolation
• Direct IF port connection enabling phase detector and bi-phase modulator functionality
• Fully hermetic packaging suitable for rigorous environmental conditions

RF Mixers Applications

• RF signal mixing in communication systems
• Phase detection circuits
• Bi-phase modulation applications

RF Mixers Procurement Notes

Verify the specific suffix PIN against official MACOM documentation to confirm package type and screening options. Ensure compatibility with MIL-STD-883 requirements if military-grade screening is specified in the procurement order. Confirm that the FP-2 hermetic package aligns with thermal and mechanical constraints of the target assembly.

RF Mixers Selection Notes

Select this component when a wide two-decade frequency range from 10 MHz to 1.5 GHz is required. Consider the low typical conversion loss of 6 dB for efficient signal processing. The direct IF connection makes it suitable for specialized modulation tasks. Verify that the 300 mW maximum input power rating meets system signal levels.

RF Mixers Part Context

This part belongs to MACOM's lineup of double-balanced mixers, sharing functional similarities with models like MDS-149 but differing in package style. The FP-2 package provides a hermetic seal distinct from surface-mount alternatives. It serves as a core component for RF front-end designs requiring high isolation and broad bandwidth coverage.

RF Mixers Replacement Considerations

MDS-149 is a documented alternative within the same family, offering identical electrical performance in an SF-1 package.
