SIW1721B Overview
The following figure shows the SiW1721B Radio Modem functional block diagram. During the receive process, the radio signal is taken from the single-ended RF input pin that feeds into the low noise amplifier (LNA). The signal from the LNA is directly down-converted to I/Q baseband,.
