HMC432ETR

Overview

The HMC432ETR is a divide-by-2 prescaler utilizing InGaP HBT technology, designed for surface-mount applications. It operates from DC to 8 GHz with a fixed division ratio of two. The device functions on a supply voltage ranging from 2.7 V to 3.3 V, typically at 3 V, drawing 42 mA of current. It delivers an output power of -3 dBm and is housed in a compact SOT-23-6 package. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Implements divide-by-2 frequency division using InGaP HBT technology
• Operates across a wide input frequency range from DC to 8 GHz
• Utilizes a low-profile SOT-23-6 surface-mount package

Applications

• RF signal processing systems requiring frequency reduction
• Wireless communication infrastructure components
• Test and measurement equipment inputs

Procurement Notes

Verify the specific suffix ETR against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as indicated in current manufacturer records. Check for active discontinuation notices or end-of-life notifications prior to procurement planning. Ensure the source document explicitly lists this part number variant to avoid substitution errors.

Selection Notes

Select this component when a static divide-by-2 function is required up to 8 GHz. Consider the SOT-23-6 footprint for space-constrained designs. Evaluate the 42 mA current consumption against system power budgets. Verify that the -3 dBm output power meets downstream stage requirements without additional amplification.

Part Context

This prescaler belongs to the HMC series of RF integrated circuits manufactured by Analog Devices. It serves as a fundamental building block for frequency synthesis and signal conditioning chains. The device represents a specialized solution for high-frequency division tasks within wireless and instrumentation markets.

Replacement Considerations

HMC432ETR is listed as a recommended substitute for the discontinued HMC432TR model.
