BUILT-IN SELF-TEST FOR RECEIVER

摘要

Representative implementations of devices and techniques provide a built-in self-test for a RF communication device. The communication device self-generates a test signal and processes the test signal through the communication device to determine an operational state of the communication device.

主权项

1. A self-test apparatus, comprising:
a radio frequency (RF) phase-locked loop (PLL) device arranged to generate a local oscillator (LO) signal; a divider component arranged to divide a frequency of the LO signal by an integer value to produce a modulation frequency; and a modulation component arranged to modulate the LO signal at the modulation frequency to produce a test signal arranged to test a system-on-chip (SoC) communication device that includes the self-test apparatus.
