PRELIMINARY CB6318
3300 to 3600 MHz Wide Instantaneous Bandwidth High-Efficiency Power Amplifier
DESCRIPTION
CB6318 is a highly efficient, wide instantaneous bandwidth, fully input/output matched power amplifier (PA) with high gain and linearity. The compact 5x5 mm PA is designed for FDD and TDD 4G LTE and 5G systems operating from 3300 to 3600 MHz.
L The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation.
IA A block diagram of the CB6318 is shown in Figure 1. The device package and pin out are shown in Figure 2.
