HMC438MS8GE

Overview

The HMC438MS8GE is a low-noise, divide-by-5 static prescaler manufactured by Analog Devices Inc. utilizing InGaP GaAs HBT technology in an 8-lead surface mount package. It operates from DC to 7 GHz with a 5 V supply voltage and draws 80 mA of current. The device provides -1 dBm output power and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Implements divide-by-5 frequency division using InGaP GaAs HBT technology for low noise performance.
• Operates as a static divider covering a wide frequency range from DC up to 7 GHz.
• Designed for surface mount integration in compact RF circuit layouts.

Applications

• Frequency synthesizer architectures requiring high-speed predivision
• Wireless communication systems operating in the microwave spectrum
• Test and measurement equipment needing broadband frequency division

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status via official documentation before procurement. Ensure storage conditions align with manufacturer specifications to maintain device integrity. Validate package marking against datasheet identifiers to prevent counterfeit substitution during assembly processes.

Selection Notes

Select this component when a divide-by-5 ratio is required for frequencies extending to 7 GHz. Consider the 80 mA supply current and 5 V operating voltage for power budget calculations. The MS8G-8 package suits applications demanding small footprint SMD solutions. Evaluate thermal management requirements given the specified operating temperature range and power dissipation characteristics.
