Analog Devices EVAL-CN0518-EBZ Evaluation Board is based on a USB-powered RF power amplifier optimized for receiving signal chains in the 915MHz ISM band. Combining two HMC376 amplifiers, the design features a gain of 25dB and return losses of more than 10dB at its center frequency. The EVAL-CN0518-EBZ circuit includes a high-speed overpower cutoff that protects sensitive downstream equipment connected to the receiver system. The receiver system also automatically returns to normal operation when the RF power level drops within the acceptable range.
The ADI EVAL-CN0518-EBZ evaluation board is intended to be used with the ADALM-PLUTO and implements a small form factor with dimensions of 25.4mm × 49.6mm x 1.5748mm (PCB only). The RF input and output are designed with a 50Ω impedance, allowing a direct connection between the circuit and standard 50Ω systems. A micro-USB connector is applied for the input power, enabling the board to use most +5V wall wart power supplies.
The EVAL-CN0518-EBZ utilizes the HMC376, a GaAs, pHEMT, MMIC, low noise amplifier with an operating frequency between 700MHz to 1000MHz. The HMC376 amplifier is ideal for GSM and CDMA cellular base station front-end receivers and requires no external matching circuitry.
