HMC525ALC4TR

RF Mixers Overview

The HMC525ALC4TR is a GaAs MMIC I/Q mixer manufactured by Analog Devices Inc. It operates within a radio frequency range of 4 GHz to 8.5 GHz, with an intermediate frequency bandwidth extending from 0 Hz to 3.5 GHz. The device features a maximum conversion loss of 11 dB and a noise figure of 8 dB. Key performance metrics include an output third-order intercept point (OIP3) of 20 dBm and a P1dB compression point of 13 dBm. Power dissipation is rated at 560 mW. It is housed in a leadless LGA-24 surface-mount package suitable for operation between -40°C and +85°C.

RF Mixers Feature Summary

• Implements dual double-balanced mixer cells integrated with a 90-degree hybrid on a single GaAs MESFET chip
• Provides high image rejection capability suitable for suppressing unwanted sidebands
• Delivers high linearity performance characterized by significant input IP3 and P1dB values

RF Mixers Applications

• Image reject mixing applications requiring specific sideband suppression
• Single sideband upconversion systems
• Point-to-point and point-to-multi-point radio links
• VSAT communication equipment

RF Mixers Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm that the received part matches the HMC525ALC4TR designation and LGA-24 package type. Ensure handling procedures account for moisture sensitivity as indicated in the datasheet. Cross-reference the manufacturer part number against internal bills of materials to prevent substitution errors during assembly.

RF Mixers Selection Notes

Select this component when designing circuits requiring wideband RF coverage from 4 GHz to 8.5 GHz with integrated image rejection. The LGA-24 package facilitates surface-mount integration. Consider the 560 mW power dissipation limit for thermal management. Evaluate the 11 dB conversion loss and 8 dB noise figure against system link budget requirements before finalizing the design.

RF Mixers Part Context

This device belongs to the HMC525A series of GaAs MMIC mixers. It utilizes two standard double-balanced mixer cells and a 90-degree hybrid fabricated in a GaAs MESFET process. The monolithic construction allows for compact implementation of complex mixing functions compared to discrete solutions.

RF Mixers Replacement Considerations

The HMC525ALC4 and HMC525ALC4TR-R5 are confirmed substitute part numbers within the same product family.
