n Tiny 6-Lead SC70 Package The LT®5534 is a 50MHz to 3GHz monolithic RF power
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
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. n APPLICATIONS n n n n L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear …
