Mini-Circuits recommends a 50-ohm microstrip line with a 0.5mm to 1.5mm wide trace and a 0.5mm to 1.5mm gap between the trace and the ground plane. A 4-layer PCB with a solid ground plane is also recommended.
Mini-Circuits recommends attaching the MAR-4SM to a heat sink or a metal plate with a thermal conductivity of at least 1 W/m-K. The heat sink should be connected to a ground plane to ensure good thermal dissipation.
The maximum operating temperature for MAR-4SM is 85°C. However, the device can be operated up to 100°C with derated performance.
Yes, MAR-4SM can be used in switching applications, but it's essential to ensure that the device is properly biased and that the switching frequency is within the recommended range (typically up to 100 kHz).
Mini-Circuits recommends using a pi-network or a T-network to match the impedance of MAR-4SM to your system. The recommended impedance matching values can be found in the application notes or by consulting with Mini-Circuits' technical support.
