Abstract :
A novel approach is proposed for direct demodulation of various digitally modulated signals at microwave/millimeter wave frequencies using a six-port phase/frequency discriminator (SPFD). The proposed six-port direct digital receiver is capable of handling PSK and QAM as well as their varieties. Preliminary measurements on demodulation of DBPSK signals at 26.5 GHz, 33 GHz and 40 GHz have revealed great potential of this new receiver
