Abstract
The invention relates to an integrated circuit (IC) comprising of a signal transmission channel (TX) including radio frequencies and a built-in tester (TEST) intended to test radio characteristics of said integrated circuit, said tester (TEST) comprising of—first means (COUPL) for recovering a part of the signal generated by the transmission channel (TX) at a first frequency (F0),—second means (M) for converting said recovered signal from the first frequency (F0) into a second frequency (F1),—an amplifier (A) for amplifying said signal at this second frequency (F1), and—a rectifier (R) for rectifying said signal.

An integrated circuit (IC) comprising a signal transmission channel (TX) including radio frequencies and an integrated tester (TEST) intended to test radio characteristics of said integrated circuit, said tester (TEST) comprising:
- first means (COUPL) for recovering a part of the signal generated by the transmission channel (TX) at a first frequency (F0),
- second means (M) for converting said recovered signal from the first frequency (F0) into a second frequency (F1),
- an amplifier (A) for amplifying said signal at this second frequency (F1), and
- a rectifier (R) for rectifying said signal.
A method of testing an integrated circuit (IC) comprising a signal transmission channel (TX) including radio frequencies, said method being intended to test radio characteristics of said integrated circuit and being independent of said transmission channel, said method comprising the following steps:
- recovering a part of the signal generated by the transmission channel (TX) at a first frequency (F0),
- converting the first frequency (F0) of the recovered signal into a second frequency (F1),
- amplifying said signal at this second frequency (F1), and
- rectifying said signal.
A tester (TEST) for testing radio characteristics of a transmission channel (TX) of an integrated circuit (IC), said tester (TEST) being intended to be integrated with said integrated circuit (IC) and comprising:
- first means (COUPL) for recovering a part of the signal generated by the transmission channel (TX) at a first frequency (F0)
- second means (M) for converting said signal recovered from the first frequency (F0) into a second frequency (F1)
- an amplifier (A) for amplifying said signal to this second frequency (F1), and
- a rectifier (R) for rectifying said signal.
