HMC361S8GTR

Overview

The HMC361S8GTR is a divide-by-2 prescaler utilizing InGaP HBT technology, designed for high-frequency signal processing applications. It operates over a frequency range of DC to 10 GHz with a nominal supply voltage of 5 V. The device draws 84 mA of operating current and delivers an output power of 3 dBm. Packaged in an 8-SOIC surface-mount format, it supports operation within a temperature range of -40°C to +85°C. This component serves as a critical element in RF signal chains requiring precise frequency division.

Feature Summary

• Implements divide-by-2 frequency division using InGaP HBT technology
• Operates across a wide bandwidth from DC to 10 GHz
• Provides stable 3 dBm output power at nominal supply conditions

Applications

• VSAT systems
• Wireless communication infrastructure
• RF signal chain design

Procurement Notes

Verify the specific package variant and revision status before procurement, as the HMC361 series includes multiple suffixes such as G8 and S8GTR which may differ in packaging or manufacturing site. Confirm end-of-life status and availability through authorized distributors, as discontinuation notices have been issued for certain variants. Ensure compatibility with existing PCB footprints and thermal management requirements for the 8-SOIC package.

Selection Notes

Select this component when a divide-by-2 function is required up to 10 GHz with low noise and stable output power. Consider the InGaP HBT technology for robust performance in VSAT and wireless applications. Verify that the 8-SOIC surface-mount package fits the design constraints and that the 5 V supply voltage aligns with the system power architecture. Evaluate thermal dissipation needs given the 84 mA current draw.

Part Context

The HMC361S8GTR belongs to the HMC361 family of prescalers from Analog Devices, which are designed for high-performance RF applications. This family utilizes InGaP HBT technology to achieve wide bandwidth and reliable operation. Other variants in the series include different division ratios and frequency ranges, but the HMC361 specifically focuses on divide-by-2 functionality up to 10 GHz, making it suitable for down-conversion stages in communication systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The HMC361S8GTR has been noted as scheduled for obsolescence. Designers should consult Analog Devices for current recommendations or alternative components within the HMC36x series that meet similar frequency and division ratio requirements.
