SGM72322A
0.4GHz to 3.8GHz DPDT Switch
GENERAL DESCRIPTION
FEATURES
The SGM72322A is a double-pole/double-throw (DPDT)
switch, which supports from 0.4GHz to 3.8GHz. The
device features low insertion loss and high isolation,
which make it suitable for high linearity and 2G/3G/4G
applications.
● Operating Frequency Range: 0.4GHz to 3.8GHz
● Supply Voltage Range: 1.7V to 3.3V
● Low Insertion Loss
● High Isolation
● Advanced Silicon-On-Insulator (SOI) Process
● Single Control Voltage Input
The SGM72322A has the ability to integrate DPDT RF
switch and GPIO controller on an SOI chip. Internal
driver and decoder for switch control signals are offered
by the GPIO controller, which makes it flexible in RF
path routing and band selection.
● GSM Power Handling
● No External DC Blocking Capacitors Required
● Available in a Green UTQFN-2×2-12AL Package
No external DC blocking capacitors required on the RF
paths as long as no external DC voltage is applied,
which can save PCB area and cost.

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performancedegradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
