HMC438MS8GTR

Overview

The HMC438MS8GTR is a divide-by-5 static frequency divider utilizing InGaP GaAs HBT technology. It operates from DC to 7 GHz with an input power range of -15 dBm to +10 dBm and a minimum input frequency of 100 MHz. The device is housed in an 8-lead surface mount package.

Feature Summary

• Implements divide-by-5 frequency division using InGaP GaAs HBT MMIC technology
• Supports wideband operation from DC up to 7 GHz
• Designed for low noise performance in RF signal chains

Applications

• Frequency synthesis systems
• RF signal processing circuits
• Wireless communication infrastructure

Procurement Notes

Verify component authenticity through authorized channels as the HMC438MS8GTR is listed as obsolete by Analog Devices. Confirm that the specific lot date code meets project requirements, noting potential availability constraints due to end-of-life status. Ensure handling precautions for electrostatic sensitive devices are observed during procurement and storage.

Selection Notes

Select this component when a fixed divide-by-5 ratio is required within the 100 MHz to 7 GHz input range. Consider the -15 dBm to +10 dBm input power tolerance for interface matching. Evaluate alternative active dividers if lower phase noise or different division ratios are needed, keeping in mind the obsolete status limits long-term supply.

Part Context

This part belongs to the HMC438 series of GaAs HBT MMIC dividers. It shares the same core functionality and package style as the HMC438MS8G and HMC438MS8GE variants. The MS8G suffix indicates a standard surface mount configuration without specific environmental qualification differences compared to the GE variant in terms of basic electrical function.
