I want to design a PSK (BPSK/DPSL/QPSK/OQPSK) modulated transmitter using FPGA based board. Output can be 70MHz IF or directly S-band modualted RF signal. Input will be 10Mbps NRZ-L serial data.
I've heard about IQ modulator which takes baseband analog input & generates RF output.
Does anyone has block diagram of IQ modualtor scheme ?
