SKY65352-11 Block Diagram Configurable transmit/receive paths Internal switching and control circuits Description Internal RF match and bias circuits The Skyworks SKY65352-11 is a high-efficiency front-end Single DC supply = 3.3 V module (FEM). The device contains a 2400 to 2500 MHz high-efficiency transmit path and a low-noise receive path. All RF ports are internally DC blocked The transmit path consists of a high efficiency power amplifier Small footprint, MCM (20-pin, 6 x 6 mm) SMT package (PA) and harmonic filter. The receive path contains a low current (MSL3, 260 C per JEDEC J-STD-020) Low-Noise Amplifier (LNA). The transmit and receive paths are connected to a common Skyworks Green products are compliant with single-pole, double-throw (SPDT) switch at both the input and all applicable legislation and are halogen-free. output. For additional information, refer to Skyworks There is an internal balun that allows either the transmit input or Denition of Green, document number the receive output to connect to a differential port. SQ04-0074. The device is mounted in a 20-pin, 6 x 6 mm Multi-Chip Module (MCM) surface-mount technology (SMT) package, which allows for a highly manufacturable low-cost solution. A block diagram of the SKY65352-11 is shown in Figure 1. The device package and pinout for the 20-pin MCM are shown in Figure 2. Signal pin assignments and functional pin descriptions are described in Table 1. Skyworks Solutions, Inc.
