HMC203

RF Mixers Overview

The HMC203 is a miniature GaAs MMIC double-balanced mixer designed for frequency conversion applications. It operates within the 14 GHz to 23 GHz range and integrates on-chip baluns to eliminate the need for external components or DC bias. The device provides high isolation between ports, with typical LO/RF isolation of 38 dB and a conversion loss of 10 dB. Its compact die size measures 1.49 x 0.89 x 0.1 mm, facilitating direct integration into MMIC hybrid circuits.

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to obsolete status in some distribution networks. Confirm package integrity and pin alignment against original datasheet specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to assembly. Validate supplier documentation matches the specific lot code and manufacturing date for traceability purposes.

RF Mixers Selection Notes

Select this component for high-frequency upconversion or downconversion tasks where minimal external circuitry is desired. The integrated baluns simplify PCB layout by removing discrete matching networks. Consider the 10 dB conversion loss when designing gain stages. Verify that the 14-23 GHz operational range aligns with system frequency requirements before implementation.
