General description

CBAT-100 it's a digitally controled attenuator, tunable in steps of 0.5dB, between 0 and 15.5dB. Within a frequency range of 0.02 to 3GHz. With a maximum limit of 23dBm power input, it is ideal for laboratory measurements such as signal control, RF amplifier tunning and mitigation of signal reflections. It can be supplied with an USB-C cable, with very low consumption of a maximum of 200mA.
