HMC6789BLC5A

Overview

The HMC6789BLC5A is a GaAs MMIC I/Q downconverter designed for the 37 to 44 GHz frequency range. It operates with a local oscillator input between 16.5 and 22 GHz, converting RF signals to an intermediate frequency of 0 to 4 GHz. The device features a minimum downconversion gain of 10 dB and utilizes a 16-terminal ceramic leadless chip carrier (LCC) package. It requires a single 3 V power supply and supports surface mount installation.

Feature Summary

• Integrated I/Q downconversion capability within a compact GaAs MMIC structure
• Operates in the Ka-band spectrum with wideband intermediate frequency output
• RoHS compliant ceramic leadless chip carrier construction for thermal stability

Applications

• Ka-band satellite communication systems
• Point-to-point microwave radio links
• Electronic warfare and signal intelligence receivers
• Test and measurement instrumentation equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm lot traceability and RoHS compliance status prior to integration. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the specific LCC-16 package variant matches the design requirements for the target application environment.

Selection Notes

Select this component when high-frequency downconversion in the 37-44 GHz range is required. The integrated I/Q architecture eliminates the need for external phase shifters. Consider the 3 V supply requirement and 150 mA current consumption during power budgeting. The ceramic LCC package offers robust performance for demanding environmental conditions compared to standard plastic packages.
