Abstract :
New RF circuit techniques have overcome the distortion problems for low supply voltages. The RF IC chip-set for the 1.9 GHz Japanese personal handy phone (PHP) system includes a low noise amplifier (GaAs MMIC), a mixer (GaAs MMIC), a linear power amplifier (GaAs MMIC), a T/R switch (GaAs MMIC), a 1.9 GHz direct-conversion quadrature modulator (Si LSI), and a frequency synthesizer (Si LSI). These components achieve very low power consumption at very low supply voltages such as 2.0 to 2.4 V
