Description
Skyworks SKY65338-21 is a high-efficiency Front-End Module
(FEM) that incorporates a transmit and receive path, and an
antenna transmit/receive (T/R) switch.
The transmit path consists of a high efficiency Power Amplifier
(PA) followed by an harmonic filter for rejection of harmonic
frequencies.
The PA is implemented using Skyworks high reliability
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 device is mounted in a 12-pin, 8 x 8 mm Multi-Chip Module
(MCM) Surface-Mounted Technology (SMT) package, which
allows for a highly manufacturable low-cost solution.
A block diagram of the SKY65338-21 is shown in Figure 1. The
device package and pinout for the 12-pin MCM are shown in
Figure 2. Signal pin assignments and functional pin descriptions
are provided in Table 1.
