Description
Skyworks SKY65336-11 is a high-efficiency Front-End Module
(FEM) for ZigBee and other 2.4 GHz ISM band applications. The
small
8 x 8 mm Multi-Chip Module (MCM) contains a 2400-2500 MHz
high-efficiency transmit path and a low-noise linear receive path.
The transmit path consists of an harmonic filter and high
efficiency Power Amplifier (PA) capable of providing +20 dBm of
power at the antenna port. Also included is an internal balun to
allow use of differential input signals.
The receive path contains a high isolation Transmit/Receive
(Tx/Rx) switch, Low Noise Amplifier (LNA), and balun for low noise
differential output.
The device is mounted in a 28-pin, 8 x 8 mm MCM Surface-
Mounted Technology (SMT) package, which allows for a highly
manufacturable low-cost solution.
A block diagram of the SKY65336-11 is shown in Figure 1. The
device package and pinout for the 28-pin MCM are shown in
Figure 2.
Skyworks offers lead (Pb)-free RoHS (Restriction of
Hazardous Substances) compliant packaging.
