Four-Channel PA IC with digital phase control targets emerging 5G
5G communications technology promises the user the perception of near infinite capacity. This requires a step change in data rates, and 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.
The 4-channel power amplifier IC design that is described offers a compact means of providing beam steering as an integral part of the PA. Each channel of the IC includes a PA with an output power capability of +30 dBm at 1 dB compression and an IP3 of +38 dBm, and includes an integral 4-bit, digitally controlled phase shifter having an rms phase error of 2.3°.
A White Paper summarizing the performance of the IC is available for free download.
