1. A phased array transceiver element comprising a local oscillator stage for generating beamformed in-phase and quadrature local oscillator signals, the local oscillator stage comprising:
a phase shifter connectable to a reference frequency source and applying a first phase shift thereto;
a primary frequency multiplier that receives input from the phase shifter and that applies a primary frequency multiplication factor thereto;
a phase-splitting arrangement that receives input from the primary frequency multiplier and that has a first output and a second output, the phase-splitting arrangement applying a second phase shift to the input from the primary frequency multiplier at the first output and applying a third phase shift to the input from the primary frequency multiplier at the second output;
a first secondary frequency multiplier that receives input from the first output of the phase-splitting arrangement, having an output that outputs the in-phase local oscillator signal, and applying a secondary frequency multiplication factor to the input from the first output of the phase-splitting arrangement; and
a second secondary frequency multiplier that receives input from the second output of the phase-splitting arrangement, having an output that outputs the quadrature local oscillator signal, and applying the secondary frequency multiplication factor to the input from the first output of the phase-splitting arrangement.
