HMC551LP4ETR

RF Mixers Overview

The HMC551LP4ETR is a double-balanced high IP3 RF mixer manufactured by Analog Devices Inc. using GaAs technology. It operates within the 800 MHz to 1.2 GHz frequency range and is housed in a 24-QFN (4x4 mm) surface-mount package. The device requires a 5 V supply voltage and draws 62 mA of operating current, with a maximum power dissipation of 600 mW. Key electrical specifications include a maximum conversion loss of 10 dB and a noise figure of 8 dB. It functions as an up/down converter for cellular applications.

RF Mixers Feature Summary

• Double-balanced architecture designed for high linearity and superior third-order intercept point performance.
• Integrated local oscillator amplifier simplifies circuit design and reduces component count.
• GaAs process technology ensures reliable operation across specified industrial temperature ranges.

RF Mixers Applications

• Cellular base station up/down converters
• 3G wireless communication systems
• GSM frequency translation circuits

RF Mixers Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Availability is restricted, and distributors may not accept orders due to temporary supply limitations. Verification of current stock status and end-of-life notices is essential before integration into new designs.

RF Mixers Selection Notes

Engineers should evaluate this part only for maintenance or legacy system repairs. New designs must consider alternative components from updated product lines, as the HMC551 series has reached its end-of-life stage. Supply chain stability is a critical factor given the discontinuation status.

RF Mixers Part Context

The HMC551 belongs to the HMC551 family of RF mixers produced by Analog Devices. These devices are characterized by their use in wireless infrastructure and mobile communication equipment. The LP4E suffix indicates the specific lead-free package variant compatible with standard surface-mount assembly processes.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct replacements require manual evaluation of newer Analog Devices mixer families or third-party equivalents based on specific RF performance requirements.
