Many who have seen the preliminary information on the IC-7300 have used terms like “Revolutionary” and “Game Changer”. How could a radio in this price category generate the amount of excitement? A new receiver design – Direct RF Sampling. But before we go into the differences and benefits of a Direct RF Sampling receiver, lets get a basic understanding of this NEW design.
Direct RF Sampling
With the advances in RF design, a new series of semiconductors are available that digitize segments of RF Spectrum. While traditional receiver designs utilize Local Oscillators, LO, these Analog to Digital converter, ADC, devices have become the heart of the IC-7300 receiver design. As you read through this blog, you are taken through a topical review of this receiver, but nothing takes the place of an actual “on air” experience. So, you will want to head to your favorite Icom dealer to “hear” this science in action!
