HMC438MS8G

Overview

The HMC438MS8G is a low noise Divide-by-5 Static Divider utilizing InGaP GaAs HBT technology in an 8-lead surface mount plastic package. It operates from DC to 7 GHz with a divide ratio of 5. The device requires a supply voltage between 4.75 V and 5.25 V, drawing 80 mA. Output power is -1 dBm. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Implements static frequency division by five using InGaP GaAs HBT technology for low noise performance.
• Operates over a wide frequency range from DC up to 7 GHz.
• Utilizes a compact 8-lead surface mount plastic package for cost-effective integration.

Applications

• Frequency synthesizer designs requiring precise division ratios
• Wireless communication systems operating in microwave bands
• Test and measurement equipment needing stable frequency references

Procurement Notes

Verify the specific suffix (G or GE) against the manufacturer's current datasheet to confirm RoHS compliance status and exact pinout configuration. Ensure the ordering part number matches the required packaging type, as tape and reel options may exist separately. Confirm that the 8-lead MS8G package fits the target PCB footprint before procurement.

Selection Notes

Select this component when a fixed divide-by-5 ratio is required within a 7 GHz bandwidth. The InGaP HBT technology offers a balance of low noise and cost efficiency compared to other MMIC technologies. Ensure the system can provide the specified 5 V supply and accommodate the 80 mA current draw. Verify input signal levels fall within the -15 dBm to 10 dBm range for optimal operation.

Part Context

The HMC438 belongs to Analog Devices' family of RF prescalers and dividers. These components are designed for wireless infrastructure and test equipment. The MS8G package is a standard small outline variant suitable for high-volume surface mount assembly processes common in modern electronics manufacturing.
