HMC8108LC5

Overview

The HMC8108LC5 is a compact, X-band, gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC) in-phase/quadrature (I/Q), low noise converter. It operates within a radio frequency range of 9 GHz to 10 GHz and supports an intermediate frequency range from 20 MHz to 1 GHz. The device provides a gain of 13 dB with a noise figure of 2 dB. Key linearity metrics include a P1dB compression point of -4 dBm and an OIP3 of 6 dBm. It functions on a single 3 V supply, drawing 40 mA of current. The component is housed in a CLCC-32 package and operates between -40 C and +85 C.

Feature Summary

• Integrates dual mixers for simultaneous I/Q signal conversion within a single GaAs MMIC structure.
• Provides balanced up/down conversion capabilities optimized for X-band applications.
• Features low noise performance suitable for sensitive receiver front-end architectures.

Applications

• X-band radar systems
• Point-to-point microwave communication links
• Electronic warfare subsystems

Procurement Notes

Verify the specific ordering suffix, such as -R5, which indicates reel packaging, against your manufacturing requirements. Confirm that the CLCC-32 package dimensions align with your PCB footprint design. Ensure thermal management strategies account for the specified operating temperature range and power dissipation characteristics during system integration.

Selection Notes
