This paper presents the first millimeter-wave wafer-scale power-amplifier array implemented in a 0.13-μ m BiCMOS technology. The power combining is done in the free-space using high efficiency on-chip antennas. A 3 × 3 power-amplifier array is demonstrated with an equivalent isotropic radiated power of 33-35 dBm at 90-98 GHz. This results in a total on-chip power of 21-23 dBm and a total radiated power of 17.5-19.5 dBm. The measured patterns of the array show single-mode operation and ~100… CONTINUE READING
