Ultra Wide Matched Input Frequency Range:
The LTC®5597 is a high accuracy RMS power detector that
100MHz to 70GHz
provides a very wide RF input bandwidth, from 100MHz n
35dB Linear Dynamic Range (< ±1dB Error)
up to 70GHz. This makes the device suitable for a wide n
28.5mV/dB Logarithmic Slope
range of RF and microwave applications, such as point- n
±2dB Flat Response from 100MHz to 60GHz
to-point microwave links, instrumentation and power n
Accurate RMS Power Measurement of High Crest
control applications.
