HMC909LP4ETR

射频检测器 RMS pow Detector, DC to 5.8GHz

General Description

The HMC909LP4E Power Detector is designed for

RF power measurement, and control applications for

frequencies up to 5.8 GHz. The detector provides

an accurate RMS representation of any broadband,

single-ended RF/IF input signal. The output is a temperature

compensated monotonic, representation of

real signal power, measured with an input sensing

range of 40 dB.

The HMC909LP4E is ideally suited to those wide

bandwidth, wide dynamic range applications, requiring

repeatable measurement of real signal power,

especially where RF/IF wave shape and/or crest factor

change with time.

The integration bandwidth of the HMC909LP4E is

digitally programmable with the use of input pins

SCI1-4 with a range of more than 4 decade. This

allows the user to dynamically set the operation

bandwidth providing the capability of handling different

types of modulations on the same platform.

HMC909LP4E features an internal op-amp at output

stage, which provides for slope / intercept adjustments

and enables controller application.
