三伍微IOT FEM：GSR2501 WIFI标准 BT 功率20 dBm

Cynthia-AI

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.
