HMC1010LP4E Functional Diagram

General Description

The HMC1010LP4E Power Detector is designed for RF power measurement, and control applications for frequencies up to 3.9 GHz. The detector provides an accurate RMS representation of any RF/IF input signal. The output is a temperature compensated monotonic, representation of real signal power, measured with an input sensing range of 60 dB.

The HMC1010LP4E 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 HMC1010LP4E is digitally programmable with the use of input pins SC I1- 4 with a range of more than 4 decades. This allows the user to dynamically set the operation bandwidth providing the capability of handling different types of modulations on the same platform.

The HMC1010LP4E features an internal op-amp at output stage, which provides for slope & intercept adjustments and enables controller application.
