GENERAL DESCRIPTION
The frequency band of operation is 824-849 MHz. The amplifier input and output are matched to provide optimum performance in a 50 Ω system. Minimal external components are required for proper RF bypassing. The tantalum capacitors, C8 and C9, are not required. Landings should be made available on the printed circuit board (PCB) as a precaution. Table 1: AWT6111 Module Pin DESCRIPTION
