Method and system for a transceiver for bluetooth and near field communication (NFC)
View Patent ↗Frequency conversion methods and systems are disclosed for a transceiver for personal area networks (PAN) and near field communication (NFC). NFC data may be received and/or transmitted via the NFC radio and PAN data may be received and/or transmitted via the PAN radio. With an integration of frequency conversion for PAN and NFC, both systems may operate from a single frequency source, thereby reducing part count and power consumption. Communication between PAN and NFC channels may be enabled via a single chip.
