GSR2701 2.4 GHz Front End Module
Product Description
The GSR2701 is an integrated front end module (FEM) designed for 2.4GHz Bluetooth, 802.11b/g/n/ac/ax systems. The device provides all the functionality of a fully matched power amplifier (PA), power detector, low-noise amplifier (LNA), and two single-pole, dual-throw (SPDT) switches.
The GSR2701 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 or to overcome the insertion loss of cellular filters (often included for mobile applications).
The GSR2701 also includes a digital enable control for transmitter power ramp on/off control. 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.
