Single chip digital transmission radio of low power consumption is a receiving and sending system on a single chip. Its sending power is about *0mW~0.5W with narrowband transmission speed (bandwidth *5k)of min **0bps and max 9.6Kbps and broadband transmission speed of hundreds of Kbps with *0k~1M bandwidth. Single chip digital transmission radio of low power is mainly used as hand equipments powered by batteries with less than **0 meters of transmission distance and no strict reliability. The advantages of the radio are low cost, low power consumption, little volume. It is applied in wireless meter reading, medical treatments and wireless LAN as commercial products. The developing trend of single chip digital transmission radio of low power is lower cost, lower power consumption and higher speed, improving radio frequency from **0M***0M to 2.4G even 5G. Model TCB***0 of high speed digitalized transmission radio is a full digitalized communication terminal equipments (Digitalized Radio) integrated by ultra short wave radio and wireless intelligence MODEM, which is developed by Tianjing Communication and Broadcasting Group Limited Company. The product adopts digital signal processing (DSP) and advanced digital communication technique mostly realized by software. Its hardware is composed of high-speed ADSP*1XX sub system, communication controlling MCU sub system, and data memory controller and output circuit. The product is automatically produced by multilayer board and SMT. Wireless intelligence MODEM of TCB***0 of high speed digitalized transmission radio is realized by advanced technique of DSP software. For example: 1. Highspeed (****0/****0/***0/***0/***0bps) data transmission is realized in *5KHz bandwidth by waveform proce
