HMC443LP4ETR

Overview

The HMC443LP4ETR is a GaAs MMIC frequency multiplier designed for high-performance RF applications. It operates as an active x4 multiplier with a fundamental input frequency range of 2.45 to 2.8 GHz and a fixed output frequency range of 9.8 to 11.2 GHz. The device integrates the multiplier circuit, bias network, and matching elements into a compact surface-mount package. It is engineered to provide stable multiplication factors across the specified bandwidth while maintaining low phase noise characteristics suitable for microwave systems.

Feature Summary

• Integrates active quadrupling functionality within a single GaAs MMIC die
• Provides direct conversion from sub-GHz input bands to Ku-band output frequencies
• Includes integrated biasing and impedance matching networks for simplified PCB layout

Applications

• Microwave point-to-point communication links
• Local oscillator generation in radar transceivers
• Satellite communication uplink/downlink modules

Procurement Notes

Verify the specific suffix 'ETR' indicates tape-and-reel packaging when sourcing components. Confirm that the GaAs technology aligns with thermal management requirements for the target application environment. Ensure that the supplier provides valid traceability documentation for the Analog Devices Inc. manufacturing origin to guarantee component authenticity and performance consistency.

Selection Notes

Select this component when a compact solution is required to generate Ku-band signals directly from lower frequency sources. Consider the power consumption and thermal dissipation capabilities of the SMD package relative to the system's cooling infrastructure. Evaluate the phase noise performance against the system's spectral purity requirements before finalizing the design integration.
