HMC258LC3B

RF Mixers Overview

The HMC258LC3B is a surface mount sub-harmonically pumped (x2) MMIC mixer operating in the 14.5 to 19.5 GHz frequency range. It features an integrated LO amplifier and utilizes a SMT leadless ceramic package. The device requires a 5 V operating supply voltage with a current consumption of 42 mA. Power dissipation is rated at 486 mW. It functions as a general-purpose RF mixer with a noise figure of 10 dB.

RF Mixers Feature Summary

• Integrates a local oscillator amplifier within the monolithic microwave integrated circuit structure
• Utilizes sub-harmonic pumping architecture for frequency conversion
• Designed for surface mount technology using a leadless ceramic package

RF Mixers Applications

• Satellite communication systems
• Point-to-point microwave links
• Electronic warfare applications

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to obsolete lifecycle status. Confirm package integrity and pin compatibility during handling. Review datasheet specifications for thermal management requirements given the power dissipation rating. Ensure supply voltage stability matches the 5 V requirement to maintain performance parameters.

RF Mixers Selection Notes

Select this component for designs requiring sub-harmonic mixing in the K-band range. Consider the integrated LO amplifier capability to simplify circuit topology. Evaluate the leadless ceramic package for thermal and mechanical suitability. Assess the 10 dB noise figure against system sensitivity requirements.

RF Mixers Part Context

This part belongs to the HMC258G series of GaAs MMIC mixers from Analog Devices. It shares architectural similarities with other sub-harmonic mixers in the portfolio, such as the HMC338LC3B, though operating at different frequency bands. The series targets high-frequency RF applications requiring compact integration.

RF Mixers Replacement Considerations

The product lifecycle status is listed as obsolete. No direct substitute part numbers are confirmed in public documentation. Designers should evaluate alternative mixers from the same manufacturer or compatible third-party components based on frequency and package constraints.
