Patent ID: 8275817

Claim:
A frequency multiplier device comprising: a plurality of multipliers, each of which has a first input port, a second input port and an output port; a first combiner coupled to said plurality of multipliers so as to receive an output signal from at least two of said plurality of multipliers, said first combiner outputting a first output signal; and a second combiner coupled to said plurality of multipliers so as to receive an output signal from at least two of said plurality of multipliers, said second combiner outputting a second output signal; wherein said plurality of multipliers includes a first multiplier, a second multiplier, a third multiplier and a fourth multiplier, said first multiplier having a first input port and a second input port and receiving a first input signal at said first input port and said second input port; said second multiplier having a first input port and a second input port and receiving a second input signal at said first input port and said second input port; said third multiplier having a first input port and a second input port and receiving said second input signal at said first input port and said first input signal at said second input port; and said fourth multiplier having a first input port and a second input port and receiving said first input signal at said first input port and said second input signal at said second input port.
