Testing the RF circuit for IoT success

Buzzwords like Industry 4.0, the internet of things (IoT), mobile computing, and cloud computing can currently be found in many headlines in magazines. The common theme throughout is the development of RF communications systems, writes Wolfgang Bartels of Rigol Technologies

By Richard Wilson - Electronics Weekly, Jun. 22, 2016 – 

Behind all these applications you will find the technologies like LTE, 3GPP, Wi-Fi, Bluetooth, ZigBee, RFID, NFC, and DECT.  Regardless of the protocol, you will find similar hardware; a receiver, a transmitter, or the combination of both - the transceiver. Input (receivers) and output stages (transmitters) typically utilize an amplifier module to help increase the signal amplitude.

With respect to this it makes sense to have a closer look at the measurements of the most important parameters of RF amplifier modules.

Each application demands different specifications and requirements. For example, the amplifier which is located in the receiver path has to be frequency selective and have low noise (LNA).
