High Dynamic Range RF Transmitter Signal Chain Using Single External Frequency Reference for DAC Sample Clock and IQ Modulator LO Generation
Progetto di riferimento di: Analog Devices
High dynamic range RF transmitter signal chain using single external frequency reference for DAC sample clock and IQ modulator LO generation. The combination of the ADRF6702 IQ modulator and the AD9122 16-bit dual 1.2-GSPS TxDAC has the dynamic range necessary for a modern high level QAM or OFDM based wireless transmitter. The dynamic range of Circuit is good enough to enable both ZIF (zero IF/baseband) and CIF (complex IF up to 200 to 300 MHz)
