A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the edge of the board to minimize signal loss. A microstrip or coplanar waveguide transmission line should be used to connect the device to the antenna.
Use a Smith chart to optimize the impedance matching. The QPM1002SR has a complex impedance of 10-j*10 ohms at 2.4 GHz. Use a pi-network or a T-network to match the impedance to 50 ohms. The values of the matching components can be calculated using a Smith chart or an impedance matching tool.
The QPM1002SR can handle up to 2W of continuous wave (CW) power. However, the device can handle higher peak powers for short durations. It's recommended to derate the power handling based on the duty cycle and pulse width of the signal.
Use a low-noise amplifier (LNA) before the QPM1002SR to reduce the noise figure. The LNA should be optimized for the frequency band of interest. Additionally, use a high-quality, low-loss transmission line to connect the LNA to the QPM1002SR.
The QPM1002SR operates from -40°C to 85°C. However, the device's performance may degrade at extreme temperatures. It's recommended to operate the device within the recommended temperature range for optimal performance.
