HMC433E

Overview

The HMC433E is a low-noise Divide-by-4 static divider utilizing InGaP GaAs HBT technology in an ultra-small surface-mount SOT26 plastic package. It operates from DC to 8 GHz with a divide ratio of 4. The device functions on a supply voltage ranging from 2.7 V to 3.3 V, typically at 3 V, drawing 53 mA of operating current. It delivers -2 dBm output power and supports temperatures from -40°C to +85°C.

Feature Summary

• Incorporates InGaP GaAs HBT technology for low noise performance
• Provides a fixed divide-by-4 static division ratio
• Operates across a wide frequency range from DC to 8 GHz
• Utilizes an ultra-small SOT26 surface-mount package

Applications

• DC to C Band PLL applications
• High-speed ADC clocking systems
• Frequency synthesis circuits

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix 'E' denotes the lead-free variant if required by assembly specifications. Review the official datasheet for handling precautions related to the small SOT26 package and electrostatic discharge sensitivity during installation.

Selection Notes

Select this component when a compact, low-noise prescaler is needed for frequencies up to 8 GHz. Ensure the application requires a fixed divide-by-4 ratio rather than programmable division. Verify that the system can accommodate the 53 mA current draw and that the SOT26 footprint fits the PCB layout constraints.

Part Context

This part belongs to the HMC433 series of static dividers designed for RF and microwave integrated circuits. It is often evaluated using demonstration boards like the DC1075B series, which also incorporate related components such as the LT1962 for complete signal chain testing in high-speed data acquisition environments.
