SX1701BI085TRT

RF Amplifiers Overview

The SX1701BI085TRT is a wideband low-noise amplifier (LNA) from Semtech Corporation, operating within a frequency range of 40 MHz to 2.5 GHz. It features a single-ended input and triple differential outputs housed in a compact 16-pin MLPQ package measuring 4 mm x 4 mm. The device provides independent programmable gain settings of 6, 12, or 18 dB per channel. Key electrical specifications include a typical noise figure of 7 dB, an output IP3 of 22 dBm, and an output IP2 of 57 dBm. It operates on a supply voltage between 4.5 V and 5.3 V with a current consumption of 130 mA when one channel is enabled.

RF Amplifiers Feature Summary

• Performs single-ended to differential signal conversion
• Offers independent programmable gain for three output channels
• Provides high linearity with elevated OIP2 and OIP3 values
• Utilizes a very small surface-mount package footprint

RF Amplifiers Applications

• Digital Set Top Boxes for Satellite and Terrestrial reception
• CATV Distribution Systems
• Active Splitter circuits
• Data Communications Systems
• Active Balun implementations

RF Amplifiers Procurement Notes

Verify the specific suffix 'BI085' against the manufacturer's official documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure that the receiving design supports the required 75 Ω input and 100 Ω differential output impedances. Confirm that the system power supply remains within the 4.5 V to 5.3 V range to maintain the specified 130 mA current consumption profile. Check for any updated lifecycle status notices directly from Semtech before finalizing procurement plans.

RF Amplifiers Selection Notes

Select this component when a wideband LNA with integrated differential conversion is required for frequencies up to 2.5 GHz. It is suitable for designs needing adjustable gain across three independent channels without external balancing networks. Consider its 7 dB noise figure and high linearity metrics for sensitive front-end applications. Ensure the PCB layout accommodates the 4 mm x 4 mm MLPQ-16 package dimensions and thermal requirements for continuous operation at maximum temperatures.

RF Amplifiers Part Context

This part belongs to the SX1701 family of highly linear wideband LNAs designed by Semtech. The series is engineered for multi-channel applications requiring single-ended to differential conversion. The SX1701BI085TRT variant specifically denotes the commercial temperature grade and packaging configuration. It serves as a core active component in RF signal processing chains where impedance matching and gain control are critical.
