HMC480ST89E

Overview

The HMC480ST89E is a wideband low-power gain block amplifier manufactured by Analog Devices Inc. utilizing InGaP HBT technology. It operates from DC to 5 GHz with a nominal gain of 19 dB and a noise figure of 3.25 dB. The device requires an 8 V supply voltage and draws 82 mA of current. Key performance metrics include a P1dB compression point of 20 dBm and an OIP3 of 36 dBm. It is housed in a surface-mount SOT-89-3 package and functions as a cascadable 50 Ohm RF/IF gain stage or local oscillator driver.

Feature Summary

• Utilizes InGaP HBT technology for high-performance amplification
• Designed as a cascadable 50 Ohm RF/IF gain stage
• Suitable for use as a local oscillator driver

Applications

• RF/IF gain stages
• Local oscillator drivers
• General purpose RF amplification

Procurement Notes

Verify component authenticity through authorized channels, as the HMC480ST89E is listed as End-of-Life (EOL) by the manufacturer. Confirm specific revision levels and RoHS compliance status directly with suppliers, as availability may be restricted to surplus stock. Ensure that any substitute components meet the original electrical specifications for frequency range and power handling.

Selection Notes

Select this component when a wideband amplifier covering DC to 5 GHz is required with moderate gain and low noise characteristics. The InGaP HBT process offers a balance of performance and power consumption suitable for portable applications. Consider the SOT-89-3 package size for space-constrained designs requiring surface-mount integration.

Part Context

This part belongs to the HMC series of monolithic microwave integrated circuits (MMICs) from Analog Devices. It represents a legacy product line originally developed by Hittite Microwave before acquisition. The ST89 suffix indicates the specific SOT-89 surface-mount package configuration used for this gain block variant.

Replacement Considerations

As the HMC480ST89E is discontinued, verify if the HMC480ST89ETR tape-and-reel version is available as a direct packaging alternative. For functional replacements, evaluate other DC-5 GHz InGaP HBT gain blocks from Analog Devices or compatible third-party manufacturers ensuring matching pinout and electrical parameters.
