RF detectors are used in an array of fields to monitor radio frequency waves.The LMV221SD/NOPB is one such RF detector; it is a comparator with two integrated non-inverting amplifiers that feature distinct characteristics. The LMV221SD/NOPB is designed for use with both low voltage single-supply and dual-supply systems, which makes it an ideal choice in radio telemetry and other applications.In radio telemetry, the LMV221SD/NOPB can be used as a power detector to monitor the power level of a received signal. The detector is capable of detecting high-frequency, narrow band signals at frequency ranges from 300 kHz to 2.7 GHz. The device can detect on average a +14.6 dBm signal within a 3 dB frequency band.The LMV221SD/NOPB works by comparing the gain and phase characteristics of two signals. A reference signal is compared to an input signal. When the two signals match, the LMV221SD/NOPB will detect the presence or absence of a signal.To ensure accuracy, the LMV221SD/NOPB utilizes both common-mode and differential-mode sensing circuitry. The common-mode sensing circuit is used for the reference signal while the differential-mode sensing circuit is used for the input signal. This combination of sensing circuitry allows the LMV221SD/NOPB to detect frequency variations and amplitude changes across its entire operating frequency range.The LMV221SD/NOPB can also detect frequency fluctuations. The device incorporates a temperature-sensing circuit that compensates for varying frequencies due to temperature fluctuations. This characteristic makes it suitable for applications where maintaining accurate frequency detection is critical. In addition, the LMV221SD/NOPB is capable of detecting both positive and negative envelope detections. These detections are performed with the same accuracy as the frequency and amplitude detections.The LMV221SD/NOPB is a powerful device and is capable of accurately detecting a range of different signals. The device is ideal for use in radio telemetry, as well as a range of other applications where accurate signal detection is critical. It is a reliable and economical option for monitoring the power level of received signals.
