ISL55008IEZ-T7

Overview

The ISL55008IEZ-T7 is a broadband RF amplifier IC from the Intersil ISL550xx series, designed for Bluetooth and general wireless applications. It operates within a frequency range of 500 MHz to 3 GHz. Key electrical specifications include a gain of approximately 16.6 dB, a noise figure of 3.9 dB, and a P1dB output power of 8.7 dBm at 3 GHz. The device is powered by a single 3.3 V supply and features integrated electrostatic discharge (ESD) protection rated at 3 kV human body model.

Feature Summary

• Integrated ESD protection capable of withstanding 3 kV human body model stress
• Broadband operation covering 500 MHz to 3 GHz frequency range
• Optimized for low-noise performance in wireless signal chains

Applications

• Bluetooth receiver front-ends
• ISM band wireless systems
• Satellite receiver signal conditioning

Procurement Notes

Verify the complete part number including suffixes such as 'IEZ' and '-T7' to ensure correct package type (SC-70-6) and tape & reel packaging configuration. Confirm RoHS compliance status and manufacturer origin (Intersil/Renesas) against current supply chain documentation to avoid counterfeit components.

Selection Notes

Select this component when a compact, low-power MMIC amplifier is required for Bluetooth or wideband RF applications. Ensure the design accommodates the 3.3 V supply voltage and SC-70-6 footprint constraints. Verify that the 3.9 dB noise figure meets system sensitivity requirements for the target frequency band.

Part Context

This part belongs to the ISL550xx family of low-power RF gain modules introduced by Intersil. These amplifiers are engineered for demanding wireless environments, offering ruggedness through built-in ESD protection while maintaining high linearity and low noise figures suitable for portable and industrial wireless devices.

Replacement Considerations

Check datasheets for alternative models within the ISL550xx series (e.g., ISL55005, ISL55007, ISL55009) if pin compatibility or specific gain/noise trade-offs differ. Verify functional equivalence regarding ESD ratings and operating temperature ranges (-40°C to 85°C).
