Skyworks SKY65352-11 is an efficient front-end module (FEM). The device contains an efficient transmission path of 2400 ~ 2500 MHz and a low noise receiving path. The transmission path consists of high efficiency power amplifier (PA) and harmonic filter.
The receiving path contains a low current low noise amplifier (LNA). The transmit and receive paths are connected to a common single pole double throw (SPDT) switch at input and output. There is an internal balun that allows the sending input or receiving output to be connected to the differential port.
The device is installed in a 20-pin, 6 x 6 mm multi-chip module (MCM) surface-mount technology (SMT) package, enabling a highly manufacturable low-cost solution. The block diagram of SKY65352-11 is shown in the following figure
The device package and pin of the 20-pin MCM are shown.
