www.DataSheet.co.kr DATA SHEET SKY65337-11: 2.4 GHz Transmit/Receive Front-End Module Applications x 2.4 GHz ISM band radios x ZigBee® FEMs x IEEE 802.15.4 applications Description Skyworks SKY65337-11 is a high-efficiency Front-End Module (FEM) for ZigBee and other 2.4 GHz ISM band applications. The small 8 x 8 mm Multi-Chip Module (MCM) contains a 24002500 MHz high-efficiency transmit path and a low-loss bidirectional path. The bidirectional path can be used to directly connect the antenna port to a directional RF port. The transmit path consists of an harmonic filter and high efficiency Power Amplifier (PA) capable of providing +20 dBm of power at the antenna port. Also included is an internal balun to allow use of differential input signals. The bidirectional path contains a high isolation transmit/receive (T/R) switch and balun for low-noise differential output. The bidirectional path can be used for either transmit or receive. The differential output receiver port is bidirectional and can be used to operate the module in a low-power transmit mode. The device is mounted in a 28-pin, 8 x 8 mm MCM SurfaceMounted Technology (SMT) package, which allows for a highly manufacturable low-cost solution. A block diagram of the SKY65337-11 is shown in Figure 1. The device package and pinout for the 28-pin MCM are shown in Figure 2.
