Functional Diagram General Descriptions
s the HMc1020LP4e Power Detector is designed for - rF power measurement and control applications for frequencies up to 3.9 GHz. the detector provides rs an accurate rMs representation of any broadband, o single-ended rF/IF input signal. the output is a tem- t perature compensated, monotonic representation of c real signal power, measured with an input sensing e range of 72 dB. t e the HMc1020LP4e is ideal y suited to those wide bandwidth, wide dynamic range applications requir- D ing repeatable measurement of real signal power, r especial y where rF/IF wave shape and/or crest factor e change with time. w the integration bandwidth of the HMc1020LP4e is o digital y programmable with the use of input pins P scI1-4 over a range of more than 3 decades. this al ows the user to dynamical y set the operation bandwidth and also permits the detection of different types of modulations on the same platform. HMc1020LP4e features an internal op-amp at the out- put stage, which provides for slope / intercept adjust- ments and enables control er application.
