Product Description

The GSR2501 is a high performance, fully integrated RF

front end module (FEM) designed for Bluetooth

(including EDR), Zigbee applications. The device

provides all the functionality of a fully matched power

amplifier (PA), low-noise amplifier (LNA), and two

single-pole, triple-throw (SP3T) switches.

The GSR2501 provides a complete 2.4 GHz WLAN RF

solution from the output of the transceiver to the antenna,

and from the antenna to the input of the transceiver. The

LNA increases the receive sensitivity of embedded

solutions to improve range. The low insertion loss and

low current bypass mode decrease the power consumption

when working in a good signal environment. The

GSR2501 also includes digital enable control pins for

power ramp on/off control.

The RF blocks operate over a wide supply voltage range

from 3.0 V to 5.2 V that allows the GSR2501 to be used

in lithium battery powered applications.

The device is provided in a compact, 16-pin 2.3 x 2.3 mm

Quad Flat No-Lead (QFN) package. Pin map is shown in

Figure 1. A functional block diagram is shown in Figure

2.
