The EVAL-CN0523-EBZ is a USB-powered, RF power amplifier that is optimized for transmitting signal chains in the 5.8 GHz ISM band. Using two HMC407 amplifiers cascaded together, the design provides a gain of 28 dB and return losses of more than 10 dB throughout its RF band of operation.
An overtemperature management feature is implemented on the EVAL-CN0523-EBZ wherein the amplifiers are automatically disabled when the board temperature reaches a preset threshold, and it automatically returns to normal operation once the temperature falls below the hysteresis point.
Designed to be used with the ADALM-PLUTO, or other software defined radio platform, the board features a small form factor, with dimensions of 25.4 mm × 50.8 mm x 1.5748 mm (PCB only). The RF input and output are designed with a 50 Ω impedance, enabling direct connection between the circuit and standard 50 Ω systems.
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.

Due to the considerable thermal dissipation of the RF amplifiers, the last three options should not be used.
Warning: Connecting the CN0523 directly to the PlutoSDR input (Rx) may result in an exceedance of its absolute maximum ratings of +2.5 dBm. Such an action may lead to permanent damage to the PlutoSDR. It is strongly recommended to use a 30 dB or 40 dB attenuator at the RX input of the ADALM PLUTO to avoid incurring damage.
