Printed Circuit boards (PCB)

The Printed Circuit Board plant is capable of producing high quality prototype and production quantities of single sided and multi-layer plater through hole circuit boards up to a maximum of six layers. Max: board size is 300mm x 250mm.

Examples of the PCBs that have been designed and implemented in the centre:

 

  • PCB layout 

A variety of circuit design and simulation tools have been used to produce printed circuit boards. E.G. the design of a microcontroller used to perform equipment configuration and control.

 

  • 60 GHz receiver 

The 60 GHz channel sounder receiver has been contructed using commercial wave guide components in conjunction with proprietary electronics. The receiver assembly includes a low noise, low distortion pre-amplifier and a single side band transltion stage to provide signals appropriate to the data acquisition system.

 

  • 6 GHz x2 multiplier 

A variety of integrated multifunction radio frequency components have been developed. Multipliers which include amplifiers and filters in addition to a multiplying device have been designed using circuit simulation tools. Circuits have been fabricated using PCB techniques on microwave substrate materials.

  • Interdigital Filter 

Three dimensional electromagnetic structures have been designed and developed including band-pass filters within the microwave frequency range. These mechanical structures have been fabricated using both manual and CNC machines.
