TM600A can realize TD-SCDMA and GSM automatic dual-mode switching, with a rich expansion interface, can be widely used in wireless fixed line, home mobile phones, low-end mobile phones, data transmission applications and other wireless terminal devices that need to support TD-SCDMA technology. Ruihe wireless communication module TM600A uses ST Ericsson (Standard Ericsson) highly integrated 67 series chipset, 67 series TD-HSPA baseband chipset is ST Ericsson's continuation of T3G's product leadership in TD-SCDMA chip field, research and development The world's first ultra-compact, ultra-low power 65nm process TD-HSPA baseband chipset. Ruihe is also one of ST Ericsson's most important partners in the field of wireless communication modules. On the one hand, the Ruihe wireless communication module TM600A can greatly reduce the overall cost and power consumption of the product, improve performance, and on the other hand, give the TD-SCDMA terminal product design more freedom in space.
