A thermal via array under the module is recommended, along with a large copper plane for heat dissipation. A minimum of 4-layer PCB with 2 oz copper is recommended. Refer to MACOM's application note AN-2171 for detailed guidelines.
The recommended biasing scheme is to use a voltage regulator to set the drain voltage (VD) to 28V, and a current source to set the gate voltage (VG) to -2.5V. Ensure the bias circuitry is decoupled from the RF path to prevent oscillations.
The maximum input power rating is 0 dBm (1 mW). Exceeding this may cause damage to the amplifier. Ensure input power is attenuated or limited to prevent damage.
Check the biasing circuitry, ensure proper decoupling, and verify the input/output impedance matching. Also, inspect the PCB layout for any defects or soldering issues. Consult MACOM's application notes and technical support for further assistance.
Yes, the MABA-009488-61HWCA is an ESD-sensitive device. Handle the module by the edges, use an ESD wrist strap or mat, and ensure the workspace is ESD-protected. Avoid touching the pins or internal components.
