DESCRIPTION
CC2590 is a cost-effective and high performance RF
Front End for low-power and low-voltage 2.4-GHz
wireless applications.
CC2590 is a range extender for all existing and future
2.4-GHz low-power RF transceivers, transmitters and
CC2590 increases the link budget by providing a
power amplifier for increased output power, and an
LNA with low noise figure for improved receiver
sensitivity.
CC2590 provides a small size, high output power RF
design with its 4x4-mm QFN-16 package.
CC2590 contains PA, LNA, switches, RF-matching,
and balun for simple design of high performance
wireless applications.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
ABSOLUTE MAXIMUM RATINGS
Under no circumstances must the absolute maximum ratings be violated. Stress exceeding one or more of the limiting values
may cause permanent damage to the device.

DEVICE INFORMATION
The CC2590 pinout and description are shown in Figure 1 and Table 1 , respectively.
PIN AND I/O CONFIGURATION

Figure 1.
The exposed die attach pad must be connected to a solid ground plane as this is the
primary ground connection for the chip. Inductance in vias to the pad should be
minimized. It is highly recommended to follow the reference layout. Changes will alter
the performance. Also see the PCB landpattern information in this data sheet.
For best performance, minimize the length of the ground vias, by using a 4-layer PCB
with ground plane as layer 2 when CC2590 is mounted onto layer 1.
