Description
RF bandwidths for cellular systems such as AMPS, TACS, GSM, TDMA, and CDMA range from 800MHz to 1.0GHz. To provide RF transmissions over this range of frequencies, Gallium Arsenide (GaAs) has become the technology of choice and offers several advantages over silicon technology: a much higher cutoff frequency, higher breakdown voltage, lower noise figure, and higher power-added efficiency. This translates to lower power dissipation and longer talk time for cellular subscribers. Single Cell Li-Ion Battery and High-Side FET Switch
