ISL55005IEZ-T7

Overview

The ISL55005IEZ-T7 is a silicon bipolar MMIC broadband amplifier manufactured by Renesas Electronics Corporation. It operates within a frequency range of 500 MHz to 3 GHz and utilizes an SC-70-6 package. The device features a Darlington configuration with high fT transistors, providing excellent thermal performance. Key electrical specifications include a noise figure of 3.6 dB and a P1dB output power of 9.5 dBm. It supports a maximum supply voltage of 6 V and functions within a temperature range of -40 °C to 85 °C.

Feature Summary

• Utilizes a Darlington configuration with high fT transistors for enhanced gain and thermal stability
• Designed as a high-performance gain block suitable for demanding RF applications
• Compliant with RoHS standards and lead-free manufacturing processes

Applications

• DVB-S LNB cable receiver systems
• Broadband RF signal amplification
• Satellite communication front-end modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'IEZ-T7' matches the required package and tape-and-reel specifications. Check for obsolete status indicators, as this part may be discontinued. Ensure compliance with current environmental regulations and regional import requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact, low-noise broadband amplifier is required for frequencies up to 3 GHz. Consider the SC-70-6 footprint for space-constrained designs. Evaluate the 3.6 dB noise figure against system sensitivity requirements. Compare performance metrics with alternative family members like the ISL55012 if higher gain or different impedance matching is needed for the specific application topology.

Part Context

The ISL55005IEZ-T7 belongs to a family of MMIC silicon bipolar broadband amplifiers that includes models such as the ISL55007, ISL55008, ISL55009, ISL55010, and ISL55011. These devices share similar architectural features, including the Darlington configuration and high thermal performance characteristics, designed primarily for DVB-S LNB cable receiver applications.

Replacement Considerations

Public documentation identifies the ISL55012 as a recommended replacement for the ISL55005 series. Verify pin compatibility and electrical parameter alignment before substitution. Consult official datasheets for both components to ensure functional equivalence in the target circuit design.
