What is NRF24L01 PA LNA?

Overview. NRF24L01P + PA + LNA wireless module operates in Free license 2.4G ISM band, you can do point to point application and can also be composed of star network.

What is the range of NRF24L01 PA LNA?

Package Includes :

Input Supply voltage (V) 3 ~ 3.6 (recommended 3.3V)
Operating Range (Km) 1
Antenna Gain (peak) (dBi) 2
Receiver sensitivity -92dBm in 2Mbps mode -95dBm in 1Mbps mode -104dBm in 250kbps mode

How does NRF24L01 communicate?

The nRF24L01+ communicates over a 4-pin SPI (Serial Peripheral Interface) with a maximum data rate of 10Mbps. All parameters such as frequency channel (125 selectable channels), output power (0 dBm, -6 dBm, -12 dBm or -18 dBm), and data rate (250kbps, 1Mbps, or 2Mbps) can be configured through the SPI interface.

How does an LNA work?

A low-noise amplifier (LNA) is an electronic amplifier that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio. An amplifier will increase the power of both the signal and the noise present at its input, but the amplifier will also introduce some additional noise.

How do I choose LNA?

Selecting an LNA involves achieving the desired cascaded NF while keeping LNA gain to a minimum to preserve the receiver linearity. A key take away is that an LNAs only purpose is to reduce the cascaded receiver NF.

How do I connect my phone to NRF24L01?

How do you power LNA?

The power to the antenna LNA is provided through the receiver’s RF port center conductor. The PwrPak7, CPT7 and OEM7 receivers, except the OEM7600, provide +5 VDC ±5% at a maximum of 200 mA. The OEM7600 provides +3.3 VDC ±5% at a maximum of 100 mA. Antenna supply over current protection limits the LNA power.

What is LNA noise figure?

A low-noise amplifier (LNA) is commonly found in all receivers. Its role is to boost the received signal a sufficient level above the noise floor so that it can be used for additional processing. The noise figure of the LNA therefore directly limits the sensitivity of the receiver.

What is the role of PA and LNA?

PA: (power amp) amplifies when transmitting. LNA: (low noise amp) amplifies when receiving. both sit between circuitry and antenna. for duplexed signal, passive duplexer shifts between the two on Rx/Tx.
