What are the new power modules for base stations

How big is a 5g-advanced base station module?

The compact module measures only 12.0mm x 8.0mm (prototype) thanks to the high-density mounting of components, which will enhance the installation efficiency of 5G-Advanced base stations. Going forward, Mitsubishi Electric will continue research and development aimed at the practical application of the PAM in 5G-Advanced base stations.

Can a two-stage Doherty power amplifier be used for MIMO base stations?

Author to whom correspondence should be addressed. In this paper, a 3.2–3.6 GHz two-stage Doherty power amplifier (PA) module is proposed for fifth-generation (5G) massive multiple-input multiple-output (MIMO) base stations. A detailed design method and procedure for a compact and low-loss combiner suitable for the Doherty PA module are introduced.

How much power does a Doherty PA module produce?

The proposed two-stage Doherty PA module achieves a 3 dB small-signal bandwidth of 3.1–3.9 GHz and a peak gain of 31.7 dB. From 3.2 to 3.6 GHz, the saturated output power is 40.4–41.1 dBm. Moreover, the measured saturated drain efficiency (DE) and 8 dB power back-off (PBO) DE reach 51–56.6% and 45.5–48.6%, respectively. 1. Introduction

How much power does a DPA module produce?

The proposed DPA module can achieve 29.6–30.4 dB small-signal gain and 40.4–41.1 dBm saturated output power among 3.2–3.6 GHz. The measured saturation drain efficiency (DE) and 8 dB power back-off (PBO) DE reach 51–56.6% and 45.5–48.6%, respectively.
