5G communications promises to offer the user the perception of near infinite capacity. This requires a step change in data rates that will be facilitated by a move to higher transmission frequencies where wider bandwidths are more readily available. New innovative components will be required to meet this demand, such as the 4-channel 28 GHz phase adjustable Power Amplifier (PA) described in this paper. Each channel has an output power capability of +30 dBm (at 1 dB compression) with an IP3 of +38 dBm and incorporates independent, 4-bit phase adjustment with an rms phase error of 2.3 degrees.
