HMC6789BLC5ATR-R5

Overview

The HMC6789BLC5ATR-R5 is a GaAs MMIC I/Q downconverter designed for the 37-40 GHz frequency range. It features a 16-pin LCC package and operates on a 3 V supply. The device provides a minimum downconversion gain of 10 dB and supports a maximum intermediate frequency of 4000 MHz. It includes a tunable local oscillator input and maintains a 50 Ω characteristic impedance. The component is rated for operation between -40 °C and +85 °C.

Feature Summary

• Integrated I/Q downconversion architecture for direct RF-to-baseband processing
• Tunable local oscillator input capability for flexible frequency planning
• GaAs MMIC construction ensuring high-frequency performance in a compact surface-mount package

Applications

• Point-to-point microwave radio systems
• Satellite communication ground stations
• Electronic warfare and signal intelligence receivers
• High-speed data link terminals

Procurement Notes

Verify current availability status as this part may be subject to limited supply or factory special order constraints. Confirm that the specific reel packaging variant matches your automated assembly requirements. Ensure compliance with RoHS3 standards if required by your manufacturing process. Cross-reference the datasheet revision date to confirm technical specifications align with your design timeline.

Selection Notes

Select this component when designing systems requiring direct conversion from the Ka-band spectrum. The integrated I/Q structure eliminates the need for external phase shifters, simplifying the RF front-end layout. Verify that the 3 V power supply constraint fits within your system's voltage regulation strategy. Consider the thermal management capabilities of the ceramic package for high-power continuous wave applications.

Part Context

This device belongs to the HMC6789 series of up/down converters manufactured by Analog Devices Inc. It utilizes Gallium Arsenide (GaAs) technology to achieve performance at millimeter-wave frequencies. The product falls under the Wireless & RF Integrated Circuits subcategory, specifically targeting high-frequency communication and radar applications where size and integration are critical.

Replacement Considerations

The HMC6789BLC5A is the non-reel version of this component. Both parts share identical electrical specifications and functionality. Choose the BLC5A variant only if manual placement or cut-tape handling is preferred over automated reel-based assembly processes.
