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.
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.
