Abstract

The present invention relates to a power monitoring circuit for use in wireless fidelity (WiFi) systems. More specifically, the invention is a low power, inexpensive radio frequency (RF) power monitoring circuit that incorporates the integrated circuit for amplification, analog-to-digital conversion, and antenna circuit into a single simple circuit.

Claims

1. An integrated radio frequency (RF) detector circuit for detecting, processing and displaying the strength of wireless signal in a particular band.

2. An integrated RF detector circuit as in claim 1, wherein a de-multi-band measurement system incorporates several resonant antennas formed into a three-dimensional arrangement for compact design.

3. An integrated RF detector circuit as in claim 1, wherein the power measuring for multiple bands uses a tunable filter for band selection that incorporates RF micro-electromechanical systems (MEMS) switches for low loss, high isolation from noise and interference, and low power consumption.

4. An integrated RF detector circuit as in claim 1, further comprising a home RF power monitoring system for optimum user friendliness of WiFi based home entertainment as stand alone or incorporated elements of communications.

5. An integrated RF detector circuit as in claim 1, further comprising simple RF monitor detectors for sensing when WiFi is active for surveillance, sensing and monitoring, in addition to wireless data access.
