α[V/dB] is the slope, α≡10[mV/dB]
P
Slope linearity: Within the dynamic range the slope α remains linear with a ±1dB tolerance.
Central frequency of operation (detection) is 488MHz±5MHz. An external inductor is used as part of the
band pass filter that defines bandwidth for the peak detector. This inductor is connected in parallel to an
on-chip capacitor, between pins 8 and 9 of the silicon RFIC.
Input impedance: 200Ω, non differential.
