Design Guide T7024
The typical application module support circuitry of the T7024 in a QFN20 package is
shown in Figure 6 on page 5, Figure 7 on page 5 and Figure 8 on page 8.
The reference design consists of a four-layer FR4 printed circuit board where the upper
layer contains the RF lines and most DC connections. The internal layers are used for
ground connections. Some DC connections are made on the backside of the application
board. The RF lines for the LNA and PA input and output are 50
1 mm and a spacing of 0.5 mm to the ground layer. A Gerber file with information of the
printed circuit is available on request.
The application board consists of 4 layers:

1. Top layer: RF-signals, 35 µm Cu. Spacing: 490 µm FRY
2. Second layer: GND, 35 µm Cu. Spacing: 550 µm FRY
3. Third layer: GND (optional), 35 µm Cu. Spacing: 490 µm FRY
4. Bottom layer: DC connections (optional), 35 µm Cu
