HMC432

Overview

The HMC432 is a low-noise divide-by-2 static prescaler utilizing InGaP GaAs HBT technology. It operates from DC to 8 GHz with a fixed division ratio of two. The device requires a supply voltage between 2.7 V and 3.3 V, typically 3 V, drawing 42 mA. It delivers -3 dBm output power and features ultra-low SSB phase noise of -148 dBc/Hz. Packaged in an SOT-23-6 surface-mount case, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Implements divide-by-2 frequency division using InGaP GaAs HBT technology for low noise performance
• Operates across a wide input frequency range from DC to 8 GHz
• Provides ultra-low single-sideband phase noise characteristics
• Utilizes a compact SOT-23-6 surface-mount plastic package

Applications

• Frequency synthesis systems requiring precise division ratios
• Phase-locked loop (PLL) reference divider stages
• Microwave measurement instrumentation
• Wireless communication infrastructure components

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the specific listing indicates non-compliance. Validate that the SOT-23-6 package matches design constraints. Ensure replacement strategies are active given discontinuation notifications. Check current stock availability through verified distributors only.

Selection Notes

Select this component when DC-to-8 GHz operation is required with minimal phase noise degradation. The fixed divide-by-2 ratio limits flexibility but ensures stability. Consider the SOT-23-6 footprint for space-constrained designs. Evaluate thermal management capabilities within the specified operating temperature range. Assess compatibility with 3 V logic levels and power consumption profiles.

Part Context

The HMC432 belongs to Analog Devices' RF integrated circuit portfolio focused on microwave signal processing. It serves as a prescaler within wireless and test equipment applications. The device leverages established InGaP GaAs HBT manufacturing processes for reliability. It complements other frequency control components in complex RF front-end architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in official documentation. The component is listed as End-of-Life with discontinuation notifications. Designers must evaluate alternative divide-by-2 prescalers with compatible frequency ranges and packaging.
