Abstract:
A signal power detection device comprising:radio frequency amplification means for attenuating and low-noise amplifying input signals; intermediate frequency amplification means for converting an output signal from said radio frequency amplification means into a desired intermediate frequency signal and detecting power of the converted intermediate frequency signal; local signal generation means for supplying to said intermediate frequency amplification means a frequency signal corresponding to said intermediate frequency signal whose power is to be detected; and digital signal processing means for digitizing said signal power detected by said intermediate frequency amplification means such that it is appropriate to an interface standard, outputting the digitized result to a portable terminal device connected thereto via an interface and supplying a desired reference frequency to said local signal generation means; said signal power detection device being of a thin card type such that it can be connected with said portable terminal device via a data interface slot.
