A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces short and away from the digital lines. Use a common mode filter or a pi-filter to reduce EMI.
Adjust the VD and VG pins to achieve a quiescent current of 10-20mA. Ensure the voltage supply is well-regulated and decoupled to minimize noise. Use a resistor divider network to set the bias voltage.
The TQP7M9101 can handle up to 2W of input power. However, it's recommended to operate at 1W or less to ensure reliable operation and minimize thermal stress.
Check the PCB layout for any signs of resonance or oscillation. Ensure the biasing is correct and the voltage supply is stable. Use a spectrum analyzer to identify any spurious signals or harmonics.
Yes, the TQP7M9101 can be used in a push-pull configuration to achieve higher power output. However, ensure the devices are properly matched and the layout is symmetrical to minimize uneven current distribution.
