The LT5538 is a 40MHz to 3800MHz monolithic logarithmic RF power detector, capable of measuring RF signals over a wide dynamic range, from –75dBm to 10dBm. The RF signal in an equivalent decibel-scaled value is precisely converted into DC voltage on a linear scale. The wide linear dynamic range is achieved by measuring the RF signal using cascaded RF limiters and RF detectors. Their outputs are summed to generate an accurate linear DC voltage proportional to the input RF signal in dBm. The LT5538 delivers superior temperature stable output (within ±1dB over full temperature range) from 40MHz to 3.8GHz. The output is buffered with a low impedance driver.
