Abstract:

An integrated circuit includes a receiver portion, a transmitter portion, and a modulated phase locked loop. The receiver portion is for receiving a radio frequency (RF) signal at a receiver input of the receiver portion. The transmitter portion is for transmitting an RF signal at a transmitter output of the transmitter portion. The modulated phase locked loop (PLL) is shared between the receiver portion and the transmitter portion. The transmitter output and receiver input are coupled together in a loopback configuration during a test mode. The transmitter portion and the receiver portion are enabled concurrently while a modulated PLL signal is provided to the receiver portion from the transmitter portion via the loopback configuration.
