Hi, Client ! I have large experiences in SCH and PCB design of embedded system with micro controllers such as FPGA, DSP, ARM, Arduino, PIC for 11 years. I have expert skill in design processing mixed signal and RF signal such as AD/DA converter, LNA, frequency down/up converter, mixer, synthesizer, PLL, RF/IF amplifier, BPSK/QPSK/QAM modem, etc. I always worked from scratch:studying on datasheet, selecting ICs, system design, sch and psb library design, sch and pcb design, manufacture physical board, and testing with firmware, HDL programming... Your job is simple and basic, so I can do enough. So I know and understand enough your requirement and will finish them in short time, high quality, without error. Your job is simple and I can do enough. I will work full time and do my best for you. Best regards!
