HMC482ST89E

Overview

The HMC482ST89E is a SiGe HBT gain block MMIC amplifier covering DC to 5 GHz. It operates at 8 V with 110 mA current consumption. Key electrical parameters include 19 dB gain, 4 dB noise figure, and 15 dB input return loss. The device delivers a P1dB of 22.5 dBm and an OIP3 of 36 dBm. Power dissipation is rated at 940 mW. It functions within a temperature range of -40°C to +85°C and utilizes an SOT-89-3 surface mount package.

Feature Summary

• Utilizes Silicon Germanium Heterojunction Bipolar Transistor (SiGe HBT) technology for high-performance RF amplification
• Designed as a monolithic microwave integrated circuit (MMIC) in a standard surface-mount package
• Capable of cascading for multi-stage RF/IF gain applications

Applications

• RF/IF gain stages in wireless communication systems
• General purpose RF amplification circuits
• Test and measurement equipment requiring wideband amplification

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'E' indicates lead-free compliance if required by assembly specifications. Check current lifecycle status as the product may be discontinued or subject to supply constraints. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component when a wide bandwidth from DC to 5 GHz is required alongside moderate gain and linearity. Compare against alternatives based on power consumption and noise figure requirements. Consider the SOT-89-3 footprint compatibility during PCB layout. Evaluate thermal management capabilities given the 940 mW power dissipation rating in the chosen enclosure.

Part Context

This part belongs to the HMC482 series of SiGe HBT gain block amplifiers manufactured by Analog Devices. It represents a legacy product line originally developed under Hittite Microwave Corporation before acquisition. The ST89 designation refers to the specific SOT-89-3 surface mount package variant. This series was designed to provide reliable performance for broadband RF applications.

Replacement Considerations

The HMC482ST89 is a compatible alternative without the environmental suffix. Verify pinout and electrical parameter equivalence before substitution. No direct cross-model replacements are officially documented in the provided data.
