The typical operating frequency range is 20–30 GHz, covering Ka-band uplink and downlink. However, the exact range depends on the specific model and application, so you must verify with the manufacturer.
Gain, typically 30–40 dBi, indicates the antenna's ability to focus energy in a particular direction. Higher gain improves the link budget, allowing for better signal quality and data rates. The actual gain must be confirmed for your specific configuration.
The subsystem is designed to operate within a temperature range of -40 to 85 °C. It includes thermal management mechanisms to maintain performance, but the exact design and materials used are specific to the model. Always check the manufacturer's specifications.
VSWR, typically ≤1.5, indicates how well the antenna is matched to the transmission line. A lower VSWR reduces signal reflection, ensuring efficient power transfer. The specified value is a reference; confirm the actual VSWR for your model.
