HMC1105

Overview

The HMC1105 is a passive miniature frequency doubler MMIC die utilizing GaAs Schottky diode technology. It operates with an input frequency range of 20 to 40 GHz, producing output frequencies of 40 to 80 GHz. The device requires no DC bias and adds no measurable additive phase noise. Typical conversion loss is 12 dB, with Fo isolation at 41 dB and 3Fo isolation at 46 dB. The die dimensions are 1.79 x 1.19 x 0.1 mm.

Feature Summary

• Passive design requiring no DC bias
• No measurable additive phase noise
• High harmonic suppression up to 46 dB typical

Applications

• Microwave test equipment
• Microwave/mmWave radios
• E-band radios
• Military and space applications

Procurement Notes

Verify the specific suffix (e.g., SX) against official Analog Devices documentation to confirm exact handling and packaging specifications. Ensure procurement channels provide genuine components from authorized sources. Confirm that the received die matches the required electrical characteristics for the target application environment.

Selection Notes

Select this component for applications requiring compact size and high isolation in millimeter-wave systems. The passive nature simplifies circuit design by eliminating bias networks. Verify compatibility with conventional die attach methods for MCM and hybrid microcircuit integration. Ensure input drive levels remain within specified limits to maintain performance.

Part Context

This part belongs to the Hittite Microwave Corporation family of MMICs, now integrated into Analog Devices. It shares technology with Hittite MMIC mixers. The HMC1105 is designed as a bare die for direct integration into substrates or modules, offering a small footprint suitable for advanced packaging technologies.

Replacement Considerations

Check for updated part numbers such as HMC1105-SX for specific packaging variants. Consult Analog Devices documentation for any discontinued status or recommended upgrades within the frequency doubler portfolio.
