Patent ID: 7924025

Claim:
An embedded s-parameter measurement system for measuring or determining an s-parameter, the system comprising: an s-parameter test circuit for connecting to a port of a high-frequency multi-port device-under-test (DUT), the s-parameter test circuit being embedded on-chip with the DUT and including: a directional coupler for sampling a forward signal at RF or microwave frequencies conveyed to the DUT and for sampling a reverse signal at RF or microwave frequencies reflected by the DUT, wherein the directional coupler connects to the DUT without a cable or external connector, a peak detector electrically connected without a cable or external connector to the directional coupler for directly detecting a magnitude of a signal at the RF or microwave frequencies of the reverse signal reflected by the DUT conveyed to the peak detector by the directional coupler, and a phase detector electrically connected without a cable or external connector to the directional coupler for determining a phase of a signal at the RF or microwave frequencies of the reverse signal reflected by the DUT conveyed to the phase detector by the directional coupler; and at least one other s-parameter test circuit for connecting to another port of the high-frequency multi-port DUT, the at least one other s-parameter test circuit being embedded on-chip with the DUT.
