One of the most instrumental pieces of RF hardware is the power amplifier (PA), a device whose importance has only increased with the proliferation of 5G. To help ease the challenges of designing RF PAs for 5G, power amplifier modules (PAMs) have become an important tool in recent years.
Yet, these radical performance improvements generate increased strain on and tighter requirements for the underlying radio frequency (RF) hardware. One of the most instrumental pieces of RF hardware is the power amplifier (PA), a device whose importance has only increased with the proliferation of 5G.
For example, in the application of a 5G base station, a PAM might integrate the driver amplifier and final stage amplifier into a single package as opposed to implementing them as discrete circuit blocks. By integrating the entire PA system onto a single module, we can achieve many important results (Figure 1).
This percentage will increase significantly with 5G because a gNodeB uses at least twice as much electricity as a 4G base station. The more operators spend on electricity, the more difficult it is to price their 5G services competitively and profitably.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
