The main reasons for using an RF module instead of doing a chip design is to reduce cost and risk. Both development cost (engineering and certification) and unit cost will be lower using a pre-made module. The risk related to investing in a development, and for successful compliance test and certification of the product, is reduced using a “known good” module solution. The time-to-market (ROI) will also be shorter.
