Functional Diagram General Description
s the HMc909LP4e Power Detector is designed for - rF power measurement, and control applications for frequencies up to 5.8 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 40 dB. t e the HMc909LP4e 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 HMc909LP4e is o digital y programmable with the use of input pins P scI1-4 with a range of more than 4 decade. this al ows the user to dynamical y set the operation bandwidth providing the capability of handling differ- ent types of modulations on the same platform. HMc909LP4e features an internal op-amp at output stage, which provides for slope / intercept adjustments and enables control er application.
