Active phased array architecture

A phased array antenna in communication with a radiating element, the phased array antenna comprising:

• a hybrid configured to receive dual linearly polarized RF signals from the radiating element, wherein the hybrid is configured to inject a phase shift and generate a +45° slant polarization intermediate signal and a −45° slant polarization intermediate signal;
• a first vector generator configured to receive the +45° slant polarization intermediate signal, wherein the first vector generator is configured to phase adjust the +45° slant polarization intermediate signal for beam steering and output a first RF intermediate signal;
• a second vector generator configured to receive the −45° slant polarization intermediate signal, wherein the second vector generator is configured to phase adjust the −45° slant polarization intermediate signal for beam steering and output a second RF intermediate signal;
• and
• an output hybrid configured to receive the first RF intermediate signal and the second RF intermediate signal and generate two RF output signals with a phase difference, wherein the two RF output signals are a composite of the first and second RF intermediate signals;
• wherein the first vector generator and the second vector generator individually comprise a first quadrant select in parallel with a second quadrant select and a first variable gain amplifier in parallel with a second variable gain amplifier.
