SKY65383-11 Block Diagram Sleep mode current: <1 A Integrated control logic Description Small footprint, MCM (28-pin, 6 x 6 mm) package The Skyworks SKY65383-11 is a high-performance, (MSL3, 260 C per JEDEC J-STD-020) transmit/receive (T/R) front-end module (FEM). The device provides a transmit power amplifier (PA) capable of transmitting greater than +30 dBm of output power at 36 percent power- added efficiency (PAE). The receive chain features a low-loss, single-pole, double-throw (SPDT) switch and a high-performance low-noise amplifier (LNA) with a 2.5 dB noise figure (NF) and 12 dB receive gain. All functionality can be controlled using a three-wire interface. The SKY65383-11 can be placed in a deep sleep mode, which draws less than 1 A of current. The device is mounted in a 28-pin, 6 x 6 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable low- 28 27 26 25 24 23 22 cost solution. 1 21 CSD GND A block diagram of the SKY65383-11 is shown in Figure 1.
