HMC599ST89ETR

Overview

The HMC599ST89ETR is a GaAs pHEMT MMIC Low Noise Amplifier designed for 75 Ohm systems operating from 50 MHz to 1 GHz. It provides 14.5 dB gain with a noise figure of 2.2 dB and an output P1dB of 19 dBm. The device features an output IP3 of +39 dBm at 250 MHz and operates on a single supply voltage of 3 V or 5 V, drawing 120 mA. Packaged in SOT-89-3, it supports cascading as a 75 Ohm RF or IF gain stage.

Feature Summary

• Built on GaAs pHEMT technology for high linearity and low noise performance
• Designed for direct integration into 75 Ohm impedance networks
• Supports operation from standard +3V or +5V bias supplies
• Capable of functioning as a cascadable gain stage

Applications

• VHF and UHF antenna signal amplification
• HDTV receiver front-end stages
• CMTS equipment signal processing
• CATV, cable modem, and DBS system integration

Procurement Notes

Verify the specific suffix (ETR) against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm that the 75 Ohm input/output impedance matches the target circuit design requirements. Check current availability status as Hittite products may have transitioned to Analog Devices manufacturing lines.

Selection Notes

Select this component when a 75 Ohm interface is required within the 50 MHz to 1 GHz range. It is suitable for applications demanding high output power stability and low noise figures. Ensure the design accommodates the SOT-89-3 thermal characteristics and the specified 120 mA current consumption under maximum load conditions.
