LT5534 50MHz to 3GHz RF Power Detector with 60dB Dynamic Range
FEATURES DESCRIPTION
n
RF Frequency Range: 50MHz to 3GHz
The LT®5534 is a 50MHz to 3GHz monolithic RF power n
Linear Dynamic Range: 60dB
detector capable of measuring RF signals over a 60dB n
Exceptional Accuracy over Temperature
dynamic range. The RF signal in a decibel scale is pre-

cisely converted into DC voltage on a linear scale. The n
Fast Transient Response:
60dB input dynamic range is achieved using cascaded RF

detectors and RF limiters. Their outputs are summed to n Single 2.7V to 5.25V Supply generate an accurate log-linear DC voltage proportional n Low Supply Current: 7mA to the input RF signal in dB. The output is buffered with a n Shutdown Current: 0.1µA low output impedance driver. The LT5534 delivers superior n Tiny 6-Lead SC70 Package temperature stability (typical output variation within ±1dB over the full temperature range). The output responds in less than 40ns to a large RF input signal.
