E-Switch recommends following a 4-layer PCB layout with a solid ground plane, and keeping the signal traces as short as possible. Additionally, it's recommended to use a 50-ohm impedance-controlled trace for the RF signal path.
To ensure reliable switching performance, E-Switch recommends using a conformal coating on the PCB, and securing the relay to the PCB using a mechanical fastener or adhesive. Additionally, consider using a relay with a higher vibration rating, such as the RDMAR16R2T-HV.
E-Switch recommends using a drive circuit with a minimum of 10mA of drive current, and a voltage of 3.5V to 5V. A recommended drive circuit is a simple transistor switch with a base resistor and a pull-up resistor to VCC.
The relay's operating lifetime can be determined by calculating the number of cycles, and referencing the relay's datasheet. The RDMAR16R2T is rated for 10 million cycles at 25°C. Consider factors such as operating temperature, switching frequency, and load conditions when estimating the relay's lifetime.
E-Switch recommends storing the relay in a dry, clean environment, away from direct sunlight and moisture. Handle the relay by the body, avoiding touching the pins or electrical components. Avoid bending or flexing the pins, and use anti-static precautions when handling the relay.
