Shenzhen Mingjiada Electronics Co., Ltd. Supply [Nordic] NRF21540-QDAA-R7 2.4GHz RF Front-End Module (FEM)


NRF21540-QDAA-R7 - Product Overviews:

NRF21540-QDAA-R7 is an RF front-end module suitable for Bluetooth Low Energy and IEEE 802.15.4 range extension. Features include a configurable gain Power amplifier (PA) in the transmit path (TX) and Low noise amplifier (LNA) in the receive path (RX). Single-ended operation on both TRX and ANT1/2 ports is supported and requires only three external components (for single antenna operation) for the RF path.


NRF21540-QDAA-R7 - Key Features:

Supports Bluetooth® Low Energy, 802.15.4, and proprietary applications

Max output power 22 dBm

Adjustable output power to ±1 dB from 5 to 21 dBm

User programmable modes for TX gain

Support for two antenna interfaces

Receive gain +13 dB

Single-ended 50 Ω matched input and output

115 mA @ +20 dBm output power

42 mA @ +10 dBm output power

Control interface via IO, SPI, or a combination of both

Supply voltage 1.7 to 3.6 V, suitable for 1.8+/-5% systems

Operating temperature -40°C to 105°C

Package variant QFN16 4 x 4 mm


NRF21540-QDAA-R7 - Applications:

Smart Home applications

Industrial and factory automation

Advanced CE remote controls

Sports and Fitness

Toys

Medical
