A low intermodulation distortion (IMD) can be achieved using a two-amplifier quadrature-combined integrated antenna, even though the individual amplifier's IMD is quite high. It is not necessary to combine four amplifiers in equal phase increments of 45° when used as an integrated antenna to cancel out all IMD terms.
