Samsung patents self-checking chip for millimeter wave radio
Samsung describes a built-in self-test system for radio frequency chips that checks both the receiver and transmitter parts. It works by sending specific test signals into the hardware to calibrate each section automatically.
In the filing’s own words
A system and a method are disclosed for built-in self-test (BIST) for a radio frequency (RF) device including a receiver block and a transmitter block. A method includes injecting a receiver tone at an input of the receiver block of the RF device, calibrating the receiver block based on the receiver tone, injecting a transmitter tone at an input of the transmitter block, and calibrating the transmitter block based on the receiver tone.
What exactly they claim (claim 1)
1. A radio frequency (RF) device, comprising: a receiver block, a transmitter block, and a built-in self-test (BIST) unit, wherein the BIST unit is configured to: inject a receiver tone at an input of the receiver block of the RF device, calibrate the receiver block based on the receiver tone, inject a transmitter tone at an input of the transmitter block, and calibrate the transmitter block based on the transmitter tone.
