Mini-Circuits provides a recommended PCB layout and footprint in their application note AN-60-012, which can be found on their website. It's essential to follow this layout to ensure optimal performance and minimize parasitic effects.
To achieve the specified 30 dB isolation, it's crucial to ensure that the device is properly terminated, and the PCB layout is designed to minimize coupling between ports. Additionally, using a good quality PCB material with low dielectric loss and proper shielding can help achieve the desired isolation.
While the datasheet doesn't specify a maximum power handling capability, Mini-Circuits recommends that the device be operated within a maximum power density of 1 W/mm² to ensure reliable operation and prevent overheating.
Yes, JTOS-300 can be used in a push-pull configuration, but it's essential to ensure that the device is properly biased and terminated to prevent oscillations and damage. Mini-Circuits provides guidance on push-pull configuration in their application note AN-60-013.
The typical phase imbalance between ports is around 5-10 degrees, but this can vary depending on the specific device and operating conditions. It's essential to characterize the device in your specific application to determine the actual phase imbalance.
