LT5537 Datasheet | Linear Technology

.. Features - - - - - - - Wide Dynamic Range RF/IF Log Detector DESCRIPTIO The LT®5537 is a wide dynamic range RF/IF detector, operational from below 10MHz to 1000MHz. The lower limit of the operating frequency range can be extended to near DC by the use of an external capacitor. The input dynamic range at 200MHz with ±3d B nonlinearity is 90d B (from - 76d Bm to 14d Bm, single-ended 50Ω input). The detector output voltage slope is nominally 20m V/d B, and the typical temperature coefficient is 0.01d B/°C at 200MHz. , LTC and LT are registered trademarks of Linear Technology Corporation.
