Mini-Circuits recommends a 4-layer PCB with a solid ground plane, and a via-stitched ground plane under the device. A low-impedance path to the ground plane is crucial for optimal performance. Refer to the application note AN-60-014 for more details.
To achieve the specified return loss and insertion loss performance, ensure that the device is properly soldered, and the PCB layout follows the recommended guidelines. Also, use a 50-ohm transmission line and a high-quality SMA connector. Avoid any discontinuities or impedance mismatches in the signal path.
The maximum power handling capability of the RMS-25MH is 2W. Exceeding this power limit may cause permanent damage to the device. Ensure that the input power is within the specified limit to maintain the device's reliability and performance.
While the RMS-25MH is designed for 50-ohm systems, it can be used in non-50-ohm systems with some performance degradation. However, the device's return loss and insertion loss may not meet the specified values. Consult with Mini-Circuits' application engineers for guidance on using the device in non-50-ohm systems.
The operating temperature range of the RMS-25MH is -40°C to +85°C. The device's performance may degrade or become unstable outside this temperature range. Ensure that the device operates within the specified temperature range for optimal performance and reliability.
