CH. 3 SD- 5200 circuit

1. SD-5200 circuit

SD-5200 circuit is composed of RF and MPU. (RF determines communication quality and performance. MPU controls

terminal performance.) RF is composed of TX and RX. TX is composed of synthesizer (Synthesizer generates TX

frequency.), VCO, Data ALC (Automatic Level Control), Power Drive, final amplification and antenna switch.
