EVAL-CN0521-EBZ

EVAL-CN0521-EBZ is a USB-powered, RF low noise amplifier (LNA) that is optimized for receiving signal chains in the 2.4GHz ISM band. Using two HMC639 amplifiers cascaded together, the design provides a gain of 21dB and return losses of more than 10dB throughout its RF band of operation. The board includes a high-speed overpower cut-off that protects sensitive downstream equipment connected to the receiver system. The receiver system also automatically turns back on when the RF power level drops within the acceptable range. The EVAL-CN0521-EBZ features the HMC639, which is a GaAs, pHEMT, high linearity, low noise amplifier operating between 0.2GHz to 4GHz for various applications such as fixed-wireless, cellular and CATV. This low-noise RF amplifier does not require any external matching circuitry to operate.
