| National Semiconductor is a leader in RF Power Detectors with a decade of experience, proven RF Detector technology, and a wide portfolio of devices. National Semiconductor offers RF Detectors with both logarithmic and linear output transfer curves including devices with frequency bandwidths ranging from 50 MHz up to 8 GHz and dynamic ranges higher than 40 dB with accuracy better than ±0.2 dB. In addition to log-amp detectors, which measure the peak RF power, National also offers Root Mean Square (RMS) RF Power detectors, which measure the actual power of the modulated signal over a period of time. In this way, it is able to accurately measure signals with high peak-to-average ratios such as those seen in WCDMA, HSPA, LTE, and WiMAX standards. This greatly simplifies the RF Power measurement because it is independent of modulation. RF Detectors are widely used in both wireless base stations and wired communications infrasctructure PA loop control to measure signal strength. |
