2.5GHz Half-Watt Amp


SKU: PA2500L Category:


The new PA2500L provides a convenient and flexible way to amplify signals from 5MHz-to 2.5GHz for a variety of RF applications. The USB Type-C port allows for easy integration into automated test environments using SCPI serial commands. Power and gain control along with temperature and voltage monitoring make this device much faster to setup and implement than competing devices. All linear regulation, gate biasing, and power-up sequencing are done internally by the onboard controller. This amplifier is powered from USB and does not need a separate adapter or input.
