HMC258LM3

RF Mixers Overview

The HMC258LM3 is a GaAs MMIC sub-harmonically pumped (x2) mixer operating in the 14 to 20 GHz frequency range. It features an integrated LO amplifier and is designed for use as an up-converter or down-converter. The device utilizes a surface-mount leadless chip carrier package, specifically a 6-SMT configuration measuring 5.08 x 5.08 mm. It operates with a supply voltage of 5V and draws a maximum current of 50mA, resulting in a max power dissipation of 386mW.

RF Mixers Feature Summary

• Sub-harmonically pumped single-ended architecture
• Integrated local oscillator amplifier
• Compact surface-mount leadless chip carrier design

RF Mixers Applications

• Up-conversion stages
• Down-conversion stages
• Microwave communication systems

RF Mixers Procurement Notes

Verify the specific suffix LM3 against official Analog Devices documentation to confirm the exact package type and pinout configuration. Ensure compatibility with 5V supply requirements and thermal management needs for the specified power dissipation limits during integration.

RF Mixers Selection Notes

Select this component when a compact solution is required for the 14-20 GHz band. The integrated LO amplifier simplifies circuit design by reducing external component count. Consider the SMT package dimensions for PCB layout constraints and verify thermal performance under continuous operation conditions.

RF Mixers Part Context

This part belongs to the HMC258 family of sub-harmonic mixers from Analog Devices (formerly Hittite Microwave). The family includes various package options such as bare die and different SMT configurations. The LM3 variant specifically denotes the surface-mount leadless chip carrier form factor suitable for automated assembly processes.

RF Mixers Replacement Considerations

Consult official substitution guides for equivalent models within the same frequency range. Verify that any alternative maintains the sub-harmonic pumping requirement and compatible supply voltage specifications.
