Channel-selective RF power sensor

A channel-selective RF power sensor comprising:

• an enclosure containing a printed circuit board having a directional coupler and a channel-selective power measurement circuit;
• said enclosure having upper and lower cavities with metallic-coated cavity surfaces that form barriers preventing energy from said directional coupler from interfering with said channel-selective power measurement circuit;
• a via wall between said directional coupler and said channel-selective power measurement circuit on said printed circuit board to provide isolation maintain directivity;
• said directional coupler is configured to obtain a sample of energy travelling on a main transmission line and provide said sample of energy directly to said channel-selective power measurement circuit, wherein said sample of energy containing a channel of interest;
• and
• said channel-selective power measurement circuit is configured to measure RF energy information for said channel of interest in said sample of energy,
• wherein said channel-selective power measurement circuit implements band-pass filtering I/Q to the channel bandwidth, applies a Hilbert transform to the quadrature channel to impose a 90° phase shift, applies a matched delay to the in-phase channel to match the Hilbert transform's group delay;
• and sums the quadrature and in-phase channels so desired signals add constructively and the image cancels destructively;
• wherein an in-phase signal and a quadrature signal of a local oscillator of said channel-selective power measurement circuit are offset from a center frequency of said channel of interest to optimize image rejection;
• wherein said channel-selective power measurement circuit implements calibration correction factors determined at the factory and stored in memory;
• said calibration correction factors comprise path-specific correction factors;
• wherein said RF energy information includes RMS power, peak power, duty cycle, crest factor, VSWR, complementary cumulative distribution function, peak, average, peak-to-average ratio, rise time, fall time, and pulse width;
• a transceiver for making available and transmitting said RF energy information.
