Wireless receiver having improved phase shifting schemes with reduced number of phase shifters

A wireless receiver comprising:

• an antenna receiving a right-handed circularly polarized (RHCP) signal and a left-handed circularly polarized (LHCP) signal;
• a first amplifier and a second amplifier coupled to said antenna;
• an intermediate summer coupled to said first and second amplifiers, and providing a first intermediate signal;
• a third amplifier and a fourth amplifier coupled to said antenna;
• an intermediate subtractor coupled to said third and fourth amplifiers, and providing a second intermediate signal;
• a V-signal summer providing a V-component output based on a sum of said first intermediate signal and said second intermediate signal;
• an H-signal subtractor providing an H-component output based on a difference between said first intermediate signal and said second intermediate signal.
