HMC483MS8G

Overview

The HMC483MS8G is a high dynamic range passive MMIC mixer featuring an integrated local oscillator amplifier. It operates within the 700 MHz to 1500 MHz frequency range and utilizes a plastic surface mount 8-lead Mini-SOIC package. The device provides high IP3 performance for signal integrity. It requires a single positive supply voltage of +5 VDC and draws a typical current of 25 mA. The component supports operation across a temperature range from -40°C to +85°C, ensuring reliability in various environments.

Feature Summary

• Integrates a local oscillator amplifier directly with the passive mixer core
• Delivers high dynamic range and high third-order intercept point (IP3)
• Utilizes a compact 8-lead Mini-SOIC surface-mount package

Applications

• Wireless infrastructure base stations
• Point-to-point microwave radio links
• Satellite communication systems

Procurement Notes

Verify component authenticity through authorized distribution channels due to obsolete lifecycle status. Confirm that the specific MS8G suffix matches the required Mini-SOIC package dimensions and pinout configuration. Ensure compatibility with existing thermal management solutions, as the exposed pad design requires proper PCB soldering for heat dissipation. Validate that the +5V supply regulation meets the specified current draw requirements to maintain stable mixer operation.

Selection Notes

Select this component when a compact solution combining LO drive and mixing functions is required. The integrated amplifier simplifies circuit design by eliminating external driver stages. Consider the 700-1500 MHz operating band for suitability in specific wireless applications. Evaluate the high IP3 specification against linearity requirements for complex modulation schemes. Verify that the surface-mount form factor aligns with automated assembly capabilities and board space constraints.
