LT5538IDD#TRPBFLinearTechnology(凌力尔特)射频检测器

The LT?5538 is a 40MHz to 3800MHz monolithic logarith-mic 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 us-ing 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.
