The significance of the D2D technology is that it has demonstrated excellent conversion performance while enabling cost-effective true Zero IF radio architecture, eliminating the need for the intermediate frequency amplifiers and filters currently required.
INTERMEDIATE FREQUENCY AMPLIFIERS (IFAs): Designed to operate in the IF frequency range typically below 500 MHz, ADI's ADL553x family (ADL5530, ADL5531, ADL5532, ADL5533 and ADL5534) of single- and dual-channel IFAs are fully specified and characterized to support applications across the most commonly used IF frequencies of 70, 140, 190, 240, and 380 MHz.
The D2D transmitter is built from standard bulk CMOS, and creates a true Zero IF architecture, eliminating the need for the intermediate frequency amplifiers and filters currently required.
