HMC-C050

Overview

The HMC-C050 is a GaAs HBT ultra-low noise amplifier module designed for operation between 2 and 18 GHz. It provides 13.5 dB of gain, a 5 dB noise figure, and +22.5 dBm output IP3. The device features an ultra-low phase noise contribution of -160 dBc/Hz at 10 kHz offset. It operates on a single +5V supply with an operating current of 80 mA and maximum power dissipation of 650 mW. The module includes field-replaceable SMA connectors and maintains 50 Ohm matched input/output impedance.

Feature Summary

• Ultra-low phase noise performance enabling superior modulation accuracy in transceiver architectures
• High dynamic range amplification with integrated low noise characteristics
• Hermetically sealed miniature module construction with field-replaceable SMA connectors

Applications

• Microwave Radio systems
• Military and Space communications
• Test Instrumentation equipment
• VSAT networks

Procurement Notes

Verify the specific revision level and connector type when ordering, as legacy documentation may reference Hittite Microwave Corporation branding prior to acquisition by Analog Devices. Confirm hermetic sealing requirements against environmental specifications. Ensure supply voltage stability matches the single +5V requirement. Check for updated datasheet revisions that may reflect manufacturing changes while maintaining functional equivalence.

Selection Notes

Select this component when wideband coverage from 2 to 18 GHz is required alongside stringent phase noise constraints. The integrated SMA connectors simplify integration into test setups or modular radio architectures compared to bare MMICs. Consider the hermetic package for harsh environment reliability where standard surface-mount packages are insufficient. Evaluate thermal management needs given the 650 mW power dissipation within the small module footprint.

Part Context

This component belongs to the HMC-C series of microwave modules originally developed by Hittite Microwave Corporation before its acquisition by Analog Devices. The series includes various functional blocks such as mixers, attenuators, and detectors covering DC to 20 GHz ranges. The HMC-C050 specifically addresses the need for high-performance low-noise amplification in a ruggedized, connectorized form factor suitable for demanding RF applications.

Replacement Considerations

HMC-C051 is a fundamental mixer module in the same series but serves a different function. No direct pin-compatible replacement is documented in the provided data. Verify compatibility with existing SMA interfaces if substituting with other HMC-C series modules.
