The CN0555 is a two-stage, USB-powered, RF low noise amplifier that is optimized for receiver signal chains in the 433.92 MHz industrial, scientific and medical (ISM) band. It provides a gain of 40 dB through its RF band of operation using two ADL5523 amplifiers cascaded together, boosting signals for various communication protocols such as ISM, MC-GSM, W-CDMA, TD-SCDMA, and LTE .
It includes a high-speed overpower cutoff that protects sensitive downstream equipment connected to the receiver system and automatically turns back on when the RF power level drops within the acceptable range.
Designed to be used with the ADALM-PLUTO, the EVAL-CN0555-EBZ features a small form-factor with dimensions of 25.4 mm x 50.673 mm x 1.5748 mm (PCB only). The reference design uses standard 50 Ohm SMA coaxial connectors for its RF signal path - for easy integration with any RF systems; a female connector is used for the RF input and a male connector is used for the RF output. Coplanar waveguides are used for the RF traces on the board, which have a characteristic impedance of 50 Ohm. A micro USB connector is used for the input power, allowing the evaluation board to use most +5 V wall-wart power supplies available in the market.
