The MA248xD series are true RMS sensors with a dynamic range of 80 dB. These power sensors can be used for average power measurements on CW, multi-tone and modulated RF waveforms such as 3G, 4G, and OFDM. The sensor architecture consists of three pairs of diodes, each one configured to work in its square law region over the dynamic range of the sensor. Therefore, it measures true RMS power regardless of the type or bandwidth of the modulation of the input signal. Option 1 provides TDMA measurement capability, calibrating one of the diode pairs for linearity over a wide dynamic range, thus making it a truly universal sensor.
