35GHz RMS Detector Breaks Through Dynamic Range Barrier
Jan 16th 2017
The LTC5596 is a high frequency, wideband and high dynamic range RMS power detector that provides accurate, true power measurement of RF and microwave signals independent of modulation and waveforms. The LTC5596 responds in an easy to use log-linear 29mV/dB scale to signal levels from –37dBm to –2dBm, at accuracy better than ±1dB error over the full operating temperature range and RF frequency range, from 200MHz to an unprecedented 30GHz. In addition, the device’s response has ±1dB flatness within this frequency range. A wider frequency range can be used, from 100MHz to 40GHz, however with slightly reduced accuracy at the frequency extremes. Its RF input is internally 50Ω matched from 100MHz to 40GHz, making the device very easy to use at any band within its useful frequency range.
