三伍微 射频PA WiFi7 5.8G/6G Wi-Fi FEM GSR5797 兼容替代SKY85797
Product Description
The GSR5797 is a highly integrated, 5 GHz front end module (FEM) incorporating a 5 GHz single-pole,three-way throw (SP3T) transmit/receive (T/R) switch, a 5 GHz low noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA) intended for 802.11ax applications and systems.
The device is provided in a compact, 16 pin 3 x 3 mm Quad Flat No Lead (QFN) package. Integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included. An integrated power detector is included to provide closed-loop power control within the system. The small form factor and integrated matching minimizes layout area in the application and greatly reduce the number of external components.
The pin configuration and package are shown in Figure 1.A functional block diagram is shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.
