Abstract:
Power mixer arrays for providing watt-level power in mobile systems. In one embodiment, a fully-integrated octave-range CMOS power mixer that occupies only 2.6 mm2 using a 130 nm semiconductor process has been demonstrated. The power mixer provides an output power of +31.5 dBm into an external 50 Ω load with a power added efficiency (PAE) of 44% at 1.8 GHz and a full power gain compression of only 0.4 dB.
