Detector operating frequency Detail

Integrated RF detector has been widely used, and whenever a higher sensitivity and stability requirements, with integrated RF detector diode detector instead of the traditional trend. Perhaps the frequency of the RF signal detector parameters when selecting the first consideration. Approaching the speed detector must be significant enough to extract the signal. It must also be able to provide a constant response over a substantial frequency range. For example, for measuring the transmission power of the mobile phone GSM detector must have the same sensitivity in the range of 880MHz to 915MHz. Two critical parameters within the sensitivity (or gain) of the frequency change ratio, and the input impedance matching. NCS5002 is a perfect example of an optimized frequency response (Figure 1). Input matching components have been integrated in the device to ensure low VSWR. Broadband structural design, can work from within and below the highest 3GHz 100MHz range. These two features ensure that the change in the frequency range is extremely small, and because it does not require additional calibration, thus simplifying the design.
