LTC6430BIUF-15#TRPBF

Overview

The LTC6430BIUF-15#TRPBF is a high linearity differential RF/IF amplifier and ADC driver manufactured by Analog Devices Inc. It operates on a single 5V supply with 800mW power consumption. The device features a 20MHz to 2000MHz bandwidth, 15.2dB gain, and 3.0dB noise figure. Key performance metrics include a P1dB of 24.0dBm and an OIP3 of 45.6dBm at 240MHz for the B-grade variant. It utilizes a 4mm x 4mm, 24-lead QFN package.

Feature Summary

• Differential architecture designed for driving high-resolution ADCs with excellent linearity beyond 1000MHz.
• Internally matched to 100Ω differential source and load impedance with on-chip bias and temperature compensation.
• Capable of functioning as a 50Ω wideband balanced amplifier or a 75Ω CATV amplifier using appropriate baluns.
• Constructed using SiGe BiCMOS process technology for repeatability and low output noise.

Applications

• Differential ADC Driver
• Differential IF Amplifier
• OFDM Signal Chain Amplifier
• 50Ω Balanced IF Amplifier
• 75Ω CATV Amplifier

Procurement Notes

Verify the specific grade designation within the part number; the 'B' suffix indicates the component does not guarantee minimum OIP3 at 240MHz, unlike the A-grade version. Confirm that the '#TRPBF' suffix denotes tape and reel packaging suitable for automated assembly processes. Ensure compatibility with the required operating temperature range of -40°C to 85°C for the intended application environment.

Selection Notes

Select this component when a fixed-gain differential amplifier is required for signal chains operating between 20MHz and 2GHz. It is suitable for applications needing direct ADC interfacing without external matching networks due to internal 100Ω termination. Consider the B-grade specification if strict OIP3 guarantees at 240MHz are not critical for the system design.

Part Context

This device belongs to the LTC6430-15 family of high linearity differential amplifiers. It is functionally related to the LTC6431-15, which offers similar performance in a single-ended configuration. The product line is characterized by its ability to drive high-speed converters while maintaining low noise and high dynamic range across a wide frequency spectrum.
