ADI CN0534 LNA Receiver Reference Design Helps 5.8GHz ISM Applications

     The CN0534 5.8GHz Low Noise amplifier (LNA) receiver reference design from Analog Devices. The compact size of the circuit provides high-gain, reliable overpower monitoring and protection, which is an added advantage for applications facing low signal strength or small coverage in the 5.8 GHz ISM band.

     The Analog Devices CN0534 LNA receiver reference design is a high performance RF receiver system with +23 dB gain optimized to operate at a center frequency of 5.8 GHz. The input is unfiltered to maintain a noise coefficient of 2 dB, but the output is equipped with a bandpass filter to attenuate out-of-band interference.

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