Description  
The SKY65342-11 is a highly efficient Front-End Module (FEM)  
that incorporates a transmit/receive (T/R) path and an antenna T/R  
switch. The transmit path consists of a high efficiency power  
amplifier (PA) followed by a harmonic filter to reject harmonic  
frequencies. The PA is implemented using Skyworks highly  
reliable Heterojunction Bipolar Transistor (HBT) process and is  
Class AB biased to provide maximum efficiency with a low  
spurious output.  
x Small, MCM (12-pin, 8 x 8 mm) package (MSL3, 260 qC per  
JEDEC J-STD-020)  
Skyworks offers lead (Pb)-free RoHS (Restriction of  
Hazardous Substances) compliant packaging.  
A high linearity and high isolation single-pole, double-throw  
(SPDT) switch is used at the common antenna interface between  
the transmit and receive paths. The receive path is a low insertion  
loss “through” path with input and output ports internally  
matched to 50 Ω.  
The SKY65342-11 FEM uses Surface Mount Technology (SMT) in  
the form of a Multi-Chip Module (MCM), which allows for a highly  
manufacturable, low-cost solution. The device is provided as a  
compact, 12-pin 8 x 8 mm MCM. A functional block diagram is  
shown in Figure 1. The pin configuration and package are shown  
in Figure 2. Signal pin assignments and functional pin  
descriptions are provided in Table 1.
