A bidirectional RF detector such as the ADL5920 can measure both incident and reflected power in units of dBm, along an RF transmission line of characteristic impedance ZO = 50 Ω. The ADL5920 is also able to subtract these two readings, directly measuring return loss in dB. What Is...
Software-defined radios (SDRs) are radio frequency transceivers designed to facilitate digital signal processing through the use of vast libraries of open-source software. Here, we assemble a simple data acquisition system whose architecture, based on SD

The rapid development of radio-frequency (RF) technologies requires tools which can efficiently monitor the electromagnetic landscape. Broadband real-time RF spectral analyzers need to operate at room temperature, with low power consumption and have a co
As well, sometimes the detector generates a significant amount of internal noise and is therefore unable to detect a weak signal. The ability of the tracker to detect a weak signal in both the absence and presence of a stronger signal is a plus. COMMUNITY SUPPORT The larger the community of...

The detector utilizes the MOS transistor's square-law characteristic in the strong inversion region to obtain the power information of the input RF signal, and its exponential characteristic in the weak inversion region to realize the linear-in-decibel output. Measured dynamic ranges are 20 dB at...
