HMC264LM3

RF Mixers Overview

The HMC264LM3 is a surface-mount sub-harmonically pumped (x2) MMIC mixer operating in the 20 to 30 GHz frequency range. It features an integrated LO amplifier requiring only -4 dBm drive power, supplied by a single +3V to +4V bias. The device provides excellent 2LO-to-RF isolation of 25 to 35 dB, eliminating the need for external filtering. It utilizes a leadless chip carrier package compatible with standard SMT processes. Key electrical specifications include a noise figure of 9 dB and operation across a temperature range of -40°C to 85°C.

RF Mixers Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and tape/reel configuration. Ensure compatibility with LM3 footprint guidelines for thermal and RF performance. Confirm that the procurement channel provides original manufacturer packaging to prevent contamination or damage to the sensitive RF contacts during handling and storage.

RF Mixers Selection Notes

Select this component when designing systems requiring direct integration of LO amplification at millimeter-wave frequencies. The sub-harmonic architecture simplifies local oscillator design by allowing half-frequency generation. Consider the specific isolation requirements and the availability of low-drive LO signals when evaluating alternative mixers. Verify PCB layout constraints match the LM3 package dimensions for optimal impedance matching.

RF Mixers Part Context

This part belongs to Analog Devices' Hittite Microwave MMIC family, designed for high-performance RF applications. The LM3 package format is standardized across multiple products to facilitate surface mount assembly. It serves as a critical building block for high-frequency transceivers where size, weight, and power efficiency are paramount constraints in aerospace and defense contexts.

RF Mixers Replacement Considerations

Check for HMC264LM3TR variant for reel packaging differences. Consult official substitution guides for pin-compatible alternatives within the same frequency band if supply chain constraints require it.
