From in-car navigation systems and dash cams to Beidou timekeeping watches, many satellite navigation products today are equipped with satellite communication chips. But what exactly are satellite communication RF chips, and how do they function? What Are RF Chips? RF chips have long been regarded as the “crown jewel” of analog chips, emphasizing their significant role.
