Are you looking for low loss, high performing antenna + filter panels for your Massive MIMO application. ? 

With the growth of mobile data usage and expectations of 5G technology, the need to expand the capacity of mobile networks is inevitable. 
Massive MIMO is a mobile access concept designed to do just that. It is based on using an excessive number of base-station antennas, relative to the number of active user devices. Do you struggle with space, volume or filter performance for your massive MIMO solution? 

When selecting Antenna panel and RF filters for your massive MIMO application, there are several critical aspects to consider; 

  • Low loss feeding network to the radiating elements
  • Carefully  designed calibration path to maximize branch equality
  • Filters with High Q value for low insertion loss
  • Out of band attenuation performance
  • Temperature compensation
  • Power handling capability
  • Low weight
  • Design for high volume production
  • Ease of integration with active part of m-MIMO solution

The technologies we use to develop Massive MIMO filters are diverse; 
Thin Metal, Ceramic Wave Guide and Air Cavity, but lately our focus has been on the thin metal technology because of the high Q /volume that can be achieved which in turn gives lowest possible insertion loss for a given rejection scenario keeping size and weight optimized.

Over time thin metal has proven to be a more viable solution for demanding specifications. 

 

Antenna+filter mMIMO panels for 5G

We have been working with a number of OEMs to develop panels for their specific m-MIMO applications;

 

 

 

 

 

Based on our unique design, with patents pending, the filters that are placed on the back side of the antenna are small size and low weight, with minimal insertion loss (e.g. n78; 0.57 dB) and excellent out of band attenuation.  The panel can be integrated using blind mate connectors to the active radio parts.
