Rf Power Detector
MS2352
RF Power Detector/Controller
Datasheet Download
Overview
The MS2352 is a low-cost chip for precise control of RF power amplifiers, operating over a frequency range of 0.1GHz to 2.5GHz with a dynamic range exceeding 50dB.
The VSET pin of the MS2352 can accept a set control voltage with an operating voltage range of 0.23V to 1.41V. To further simplify the application of the MS2352, the input resistance of the VSET pin is greater than 1MΩ.
The MS2352 uses internal AC coupling and provides an output voltage VAPC that can be directly connected to the gain control pin of most mobile phone power amplifiers. This output has a wide operating voltage range from 160mV to (VPOS-0.3)V and can support load currents up to 6mA.
