HMC6789BLC5ATR

Overview

The HMC6789BLC5ATR is a GaAs MMIC I/Q downconverter designed for the 37 to 40 GHz frequency range. It operates with a minimum RF input frequency of 37,000 MHz and a maximum of 44,000 MHz. The device features a minimum downconversion gain of 10 dB and supports a local oscillator (LO) that is tunable. It utilizes a ceramic leadless chip carrier package with 16 terminals. The component functions within a temperature range of -40 °C to +85 °C and requires a 3 V power supply. It is RoHS compliant and constructed using GaAs technology.

Feature Summary

• Integrated I/Q downconversion architecture for quadrature signal processing
• Compact GaAs MMIC construction in a ceramic leadless chip carrier package
• Tunable local oscillator capability for flexible frequency operation

Applications

• Millimeter-wave communication systems
• Satellite communication transceivers
• Radar receiver front-ends

Procurement Notes

Verify current availability status as distribution channels may indicate limited supply or factory special order conditions. Confirm package type matches design requirements, noting variations between tape-and-reel and cut-tape formats. Ensure compatibility with existing thermal management solutions given the specified operating temperature range. Validate that the 3 V supply voltage aligns with system power constraints before integration.

Selection Notes

Select this component when designing receivers for the 37 to 40 GHz band requiring integrated I/Q demodulation. Consider the 10 dB minimum gain and 3 V supply requirements against system noise and power budgets. Evaluate the ceramic LCC package for suitable PCB footprint and thermal dissipation needs. Compare performance against other GaAs MMICs if broader frequency coverage or different gain specifications are necessary.

Part Context

This part belongs to the HMC6789 series of up/down converters manufactured by Analog Devices Inc. It is categorized under wireless and RF integrated circuits. The device represents a specialized solution for high-frequency applications where compact size and monolithic integration are critical. It complements other components in millimeter-wave subsystems by providing direct conversion capabilities.

Replacement Considerations

The HMC6789BLC5A is the non-trimmed version of this component. Verify if the specific trimming or binning associated with the 'TR' suffix is required for the application. Both parts share identical electrical specifications and pinout configurations.
