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.
