HMC773LC3B

RF Mixers Overview

The HMC773LC3B is a general-purpose double-balanced mixer designed for upconversion and downconversion applications within the 6 GHz to 26 GHz frequency range. Packaged in a leadless, RoHS-compliant 12-lead ceramic SMT package measuring 3x3 mm, this GaAs MMIC requires no external components or matching circuitry. It operates without DC bias, eliminating the need for power supply connections. Key electrical characteristics include an input IP3 of +22 dBm, LO/RF isolation of 38 dB, and a wide IF bandwidth extending from DC to 8 GHz. The device dissipates 210 mW of power.

RF Mixers Feature Summary

• General-purpose double-balanced mixer architecture suitable for both upconverter and downconverter roles
• Passive operation requiring no DC bias voltage or current
• Integrated design eliminating the need for external matching circuits or discrete components
• Wide intermediate frequency bandwidth supporting baseband to microwave signals

RF Mixers Applications

• Point-to-point radio systems
• Point-to-multi-point radios and VSAT networks
• Test equipment and sensor interfaces
• Military end-use applications

RF Mixers Procurement Notes

Verify component authenticity through authorized channels as the HMC773LC3B is officially obsolete and no longer manufactured by Analog Devices Inc. Confirm replacement compatibility with the direct substitute HMC773ALC3B if sourcing new units. Ensure handling procedures account for Moisture Sensitivity Level (MSL) 3 classification to prevent package damage during assembly. Review technical documentation for any specific layout requirements associated with the 12-CSMT package.

RF Mixers Selection Notes

Select this component for high-frequency RF mixing tasks between 6 GHz and 26 GHz where passive operation simplifies system design. The absence of DC bias requirements reduces power consumption and board complexity. Consider the 3x3 mm footprint for space-constrained layouts. Evaluate the +22 dBm input IP3 and 38 dB isolation against system linearity and leakage specifications. Verify that the DC to 8 GHz IF bandwidth aligns with the intended signal processing chain.

RF Mixers Part Context

The HMC773 series represents a family of GaAs MMIC mixers developed by Hittite Microwave Corporation, now part of Analog Devices Inc. The HMC773LC3B variant specifically denotes the leadless surface-mount version compliant with RoHS standards. This product line targets millimeter-wave applications requiring compact, high-performance mixing solutions without external tuning elements. The LC3B suffix identifies the specific ceramic package configuration used in this model.

RF Mixers Replacement Considerations

The HMC773ALC3B is listed as a direct substitute for the obsolete HMC773LC3B. Both devices share identical functional specifications and package dimensions. Verify pinout compatibility and thermal characteristics when transitioning to the replacement part number.
