Implement RF ICs on a PCB

As in most cases, when designing mixed technology, the RF modules had been designed on specialised RF design tools and after being tweaked into perfection, the circuit was presented to the board design team who now had to fit the RF module onto an already overcrowded PCB. The digital and analogue engineers would express concerns that RF energy will leak into their circuits and jeopardise safe operation. As if magic, the RF engineers have the exact same concerns—from the opposite point-of-view. To make matters worse, the only means of integration between RF design and board design was by ASCII IFF translators.

This had led to that form of integration referred to as "voice operated cursor" (RF designer commands the mouse arm of the PCB designer). Not only did this add significant time to the project but in addition, both the RF designer and the PCB designer spent significant time doing the same job. This story was especially common when the RF designers had to design custom metal shapes for their RF circuits.
