HMC522

RF Mixers Overview

The HMC522 is a compact GaAs MMIC I/Q mixer designed for high-performance RF applications. It operates within an RF frequency range of 11 GHz to 16 GHz and supports an IF bandwidth from DC to 3.5 GHz. The device features wide IF bandwidth, image rejection of 35 dB, and LO to RF isolation of 45 dB. It delivers a typical input IP3 of +24 dBm and maximum conversion loss of 10 dB. The component is suitable for VSAT systems and digital radio implementations.

RF Mixers Feature Summary

• Compact I/Q MMIC mixer architecture utilizing two standard double balanced mixer cells and a 90 degree hybrid in a GaAs MESFET process
• Capable of functioning as either an Image Reject Mixer or a Single Sideband Upconverter
• Provides significant image rejection and local oscillator to radio frequency isolation for signal integrity

RF Mixers Applications

• Point-to-Point Radio Systems
• Point-to-Multi-Point Radio Systems
• Digital Radio Applications
• VSAT (Very Small Aperture Terminal) Systems

RF Mixers Procurement Notes

Verify the specific package variant, such as HMC522LC4, against design requirements. Confirm that the GaAs MMIC die requires appropriate mounting in a 50 Ohm test fixture or custom PCB layout with bond wires for accurate performance validation. Ensure supply chain sources are authorized distributors to guarantee component authenticity and compliance with RoHS standards.

RF Mixers Selection Notes

Select this component when a small form factor alternative to hybrid style assemblies is required for image rejection or single sideband upconversion tasks. Evaluate the 11-16 GHz operational range against system frequency needs. Consider the +24 dBm input IP3 and 10 dB conversion loss metrics for link budget calculations. Verify compatibility with DC to 3.5 GHz IF outputs for downstream processing stages.

RF Mixers Part Context

The HMC522 belongs to the family of GaAs MMIC mixers produced by Analog Devices Inc., formerly Hittite Microwave Corporation. It serves as a specialized integrated circuit solution for microwave frequencies, replacing larger discrete or hybrid components. The device integrates quadrature hybrids and mixer cells on a single chip to achieve high performance in a reduced footprint compared to traditional assembly methods.
