HMC433TR

Overview

The HMC433TR is a low-noise Divide-by-4 static frequency divider utilizing InGaP GaAs HBT technology. It operates from DC to 8 GHz with a divide ratio of 4. The device requires a supply voltage between 2.7 V and 3.3 V, typically operating at 3 V. It draws 53 mA of current and delivers an output power of -2 dBm. Packaged in an SOT-23-6 surface-mount format, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Implements divide-by-4 frequency division using InGaP GaAs HBT technology for low noise performance.
• Operates across a wide frequency range from DC up to 8 GHz.
• Designed for ultra-small surface-mount SOT-23-6 packaging.

Applications

• PLL applications in C Band
• RF prescaler circuits
• Frequency synthesis systems

Procurement Notes

Verify component authenticity through authorized channels as the part may be subject to limited supply or discontinuation notices. Confirm RoHS compliance status and specific package variants (Cut Tape vs Reel) against official Analog Devices documentation prior to integration. Ensure thermal management aligns with the specified -40°C to +85°C operating range.

Selection Notes

Select this component when a divide-by-4 function is required up to 8 GHz with minimal noise contribution. The InGaP HBT technology offers advantages in linearity and noise figure compared to standard GaAs processes. Consider the SOT-23-6 footprint for space-constrained designs requiring high-frequency division capabilities.

Part Context

The HMC433 belongs to Analog Devices' family of RF and microwave integrated circuits. It serves as a prescaler for phase-locked loop (PLL) systems, enabling frequency multiplication and synthesis in wireless communication infrastructure. The device complements other mixers and switches in the portfolio for complete RF front-end solutions.

Replacement Considerations

Check for HMC433E variant which shares similar specifications but may differ in suffix designation. Verify if newer generation dividers from Analog Devices offer improved noise performance or pin compatibility for direct replacement in existing layouts.
