Analog Devices CN0534 LNA Receiver Reference Design

     CN0534 5.8 GHz Low Noise Amplifier (LNA) receiver reference design of Analog Devices. The circuit is compact in size and can provide high gain and reliable over power monitoring and protection functions. This is an additional advantage for 5.8 GHz ISM band applications facing low signal strength or small coverage.

     Analog Devices CN0534 LNA receiver reference design is a high-performance RF receiver system with a gain of+23 dB, which can work at 5.8 GHz center frequency after optimization. Its input is unfiltered, maintaining a noise figure of 2 dB, but the output is equipped with a band-pass filter, which will attenuate out of band interference

     The CN0534 circuit includes a high-speed over power detector and switch to protect the downstream sensitive equipment connected to the receiver system. When the RF power level drops to an acceptable range, the receiver system automatically resumes normal operation. RF input and output are standard SMA connectors, and the entire design is powered by a micro USB connector.
