DESCRIPTIO
The LT
detector capable of measuring RF signals over a 60dB
dynamic range. The RF signal in a decibel scale is precisely
converted into DC voltage on a linear scale. The 60dB input
dynamic range is achieved using cascaded RF detectors
and RF limiters. Their outputs are summed to generate an
accurate log-linear DC voltage proportional to the input RF
signal in dB. The output is buffered with a low output
impedance driver. The LT5534 delivers superior tempera-
ture stability (typical output variation within ±1dB over the
full temperature range). The output responds in less than
40ns to a large RF input signal.
