The LMS6002D device offers a choice of three low noise amplifiers (LNAs). A general broadband input stage is designed to handle RF inputs across the spectrum from 300 MHz to 3.8 GHz. Two further LNAs are optimized for enhanced performance for signals in the range 300 MHz to 1.5 GHz (Lo LNA) and 1.5 to 3.8 GHz (Hi LNA). The mixer in the receive path uses the same PLL clock input as the transmitter, but has a different synthesizer to provide full duplex and direct down conversion. Programmable gain stages and filtering are applied, before the analog signal is digitized and output as I&Q data streams.
