HMC433ETR

Overview

The HMC433ETR is a divide-by-4 prescaler manufactured by Analog Devices Inc., utilizing InGaP HBT technology. It operates from DC to 8 GHz with a supply voltage range of 2.7 V to 3.3 V and an operating current of 53 mA at 3 V. The device delivers -2 dBm output power and is housed in an SOT-23-6 surface-mount package. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Implements divide-by-4 frequency division using InGaP HBT technology
• Supports direct connection to PLL synthesizers without external buffers
• Operates over a wide frequency range from DC to 8 GHz

Applications

• Direct connection to phase-locked loop (PLL) synthesizers
• Frequency synthesis for wireless communication systems
• Test and measurement equipment requiring high-frequency division

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status as indicated in official documentation, noting potential variations in regulatory markings. Check for end-of-life notifications or discontinuation notices prior to procurement decisions. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Selection Notes

Select this component when a divide-by-4 prescaler is required for frequencies up to 8 GHz. Consider the SOT-23-6 package size for space-constrained designs. Verify that the 53 mA supply current fits within the system power budget. Ensure the operating voltage range of 2.7 V to 3.3 V aligns with the available power rails in the application circuit.

Part Context

The HMC433ETR belongs to Analog Devices' HMC series of RF integrated circuits, specifically designed for microwave and millimeter-wave applications. This prescaler is part of a family of components aimed at simplifying PLL design by integrating buffer amplifiers. It complements other RF building blocks like mixers and amplifiers in communication subsystems.

Replacement Considerations

Consult official Analog Devices documentation for qualified replacement parts. Verify pin compatibility and electrical specifications before substitution. Generic equivalents may not meet the specific InGaP HBT performance characteristics required for DC to 8 GHz operation.
