HMC-C045

Overview

The HMC-C045 is a GaAs MMIC PHEMT low noise amplifier housed in a miniature, hermetic module. It operates within the 1.8 to 4.2 GHz frequency range. The component provides 26 dB of gain and achieves a noise coefficient below 1 dB. This high dynamic range amplifier features replaceable SMA connectors for integration flexibility.

Feature Summary

• Utilizes GaAs MMIC PHEMT technology for signal amplification
• Encased in a miniature, hermetically sealed module
• Designed with replaceable SMA connectors for interface adaptability

Applications

• RF receiver front-end stages
• Satellite communication systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific manufacturer source, as Analog Devices acquired Hittite Microwave Corporation. Confirm that the ordering part number corresponds to the hermetic module variant rather than bare die or other package styles. Ensure compatibility with the required SMA connector type and verify RoHS compliance status for the specific production batch before finalizing procurement orders.

Selection Notes

Select this component when a low noise figure under 1 dB is critical for system sensitivity. The 26 dB gain supports direct connection to subsequent mixer stages without intermediate amplification. Consider the hermetic packaging requirements for harsh environments where standard plastic packages may fail. Evaluate the physical size constraints against the available board space for the miniature module form factor.

Part Context

This device belongs to the HMC series of microwave monolithic integrated circuits originally developed by Hittite Microwave Corporation. Following the acquisition by Analog Devices, these products are managed under the Analog Devices portfolio. The HMC-C045 specifically targets applications requiring reliable low-noise performance in the L-band and S-band frequencies.

Replacement Considerations
