       The Qorvo QPL1820EVB01 evaluation board is now available from Mouser and is a demonstration and development platform for the QPL1820 75 ohm cable amplifier. It offers a frequency range of 50MHz to 1800MHz, making it an ideal solution for broadband CATV DOCSIS 4.0 applications, including nodes, amplifiers and remote PHY devices, as well as FTTH, home gateways and cable modems. The device is also a superlinear GaAs pHEMT differential RF amplifier with a flat gain of 22dB. 

     The circuit board provides an example application circuit that enables rapid prototyping when integrated into existing designs. The evaluation board is supplied with a pre-installed QPL1820 5mm x 5mm laminate module. The 75-ohm F-connector provides RFIN and RFOUT, and the header allows access to critical signals.
