MACOM recommends a 4-layer PCB with a solid ground plane, and thermal vias under the device to dissipate heat. A thermal pad on the bottom of the package should be connected to a heat sink or a thermal management system.
MACOM recommends using a resistive divider network to set the bias voltage, and a decoupling capacitor to filter out noise. The bias voltage should be set to 3.3V to 5V, and the current limit should be set to 500mA to 1A.
MACOM recommends using a pi-network or a T-network for input and output matching, with a characteristic impedance of 50 ohms. The network should be designed to match the device's input and output impedance to the system's impedance.
The device has a built-in thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. The overcurrent protection feature limits the current to 1.5A. The host system should monitor the device's temperature and current, and take corrective action if necessary.
MACOM recommends using ESD protection devices such as TVS diodes or ESD arrays to protect the device from electrostatic discharge. The device should be handled in an ESD-controlled environment, and users should wear ESD-protective wrist straps or mats.
