NT1741 Bluetooth LE Rx Booster

Introduction

The NT1741FBAE2S is a Bluetooth Low Energy receiver booster from Nisshinbo Micro Devices for 2.4 GHz wireless designs. Part of the NT1741 series, it combines a high-gain low-noise amplifier (LNA) with a transmit bypass path in a low-current RF front-end device.

Operating across the 2.4 GHz to 2.5 GHz ISM band used by Bluetooth Low Energy, the device is intended to support BLE receiver designs where sensitivity, communication stability, and wireless range are important considerations.

What it does

The NT1741FBAE2S amplifies received signals in the BLE band through its integrated LNA, specified with 13 dB typical gain and a 2.3 dB noise figure. These characteristics make it a receiver-side RF front-end option for designs requiring gain while keeping added noise low.

A transmit bypass path is integrated alongside the LNA, allowing the device to support systems that alternate between receive and transmit operation. Current consumption is specified at 1.5 mA in LNA mode and 1 µA in bypass mode, emphasizing low current draw in both operating states.

Applications

• Bluetooth Low Energy sensor nodes and wireless peripherals
• BLE devices requiring an RF receive-path gain stage
• 2.4 GHz ISM-band wireless products with transmit/receive operation
• Low-current BLE designs where bypass-mode consumption is relevant
• BLE links where receiver sensitivity and communication stability are design priorities

Design considerations

The NT1741FBAE2S is specified for the 2.4 GHz to 2.5 GHz ISM band, so it should be considered for RF paths operating within that frequency range rather than for broader-band wireless coverage.

Its receive-path characteristics—13 dB typical gain and a 2.3 dB noise figure—should be evaluated in the context of the complete RF chain, including the antenna, filtering, matching network, transceiver, and PCB layout. The integrated transmit bypass path is relevant for BLE architectures that need a low-current path during transmit operation.

The product is supplied in reel packaging, with a factory pack quantity of 5,000 units. Package and mounting details are not provided in the available component data and should be confirmed from the datasheet before PCB and assembly planning.
