PTX130W数据手册Renesas中文资料规格书

描述 Description

The PTX130W is a powerful and efficient NFC transmitter system-on-chip for NFC wireless charging applications alongside data communication. PTX130W features improved key performance parameters such as output power and RX sensitivity (-80dBc ). While eliminating EMC filter and matching components the PTX130W enables simple integration and compact design without the complexity associated with existing solutions (dual resonating circuits composed by EMC filter and antenna). The superior RF performance of PTX130W enables small antenna design, fast charging and allows flexible placement of Poller and Listener antennas.
