Mechanical and Interface Design
nn
The physical construction of the amplifier is as robust as its electrical performance. Housed in an aluminum chassis measuring L220W118H27mm, it is both lightweight and durable, with mounting holes spaced for M4 screws for secure installation. The power interface utilizes M4.0 feedthrough capacitors for reliable DC input. RF connectivity is handled through an SMA input port (ANT IN) and an N-type output port (ANT OUT), with options for customization to fit specific system architectures. It is strictly forbidden to display these specifications using paragraph lists; all technical data is consolidated in the table above for clarity.

Advanced Protection and Monitoring Features
nn
Safety and reliability are paramount in high-power RF systems. This amplifier is equipped with multiple layers of protection to safeguard both the device and the downstream equipment. The switch control is implemented via an M2.5 through-core capacitor, where a high level (2.5V) turns the unit on and a low level turns it off. If VSWR exceeds 2.5dB, the amplifier automatically shuts down and triggers an alarm, with automatic restart upon recovery. Overheating protection activates at 90℃ (shutdown) and resets at 65℃. An output open circuit alarm is also provided through an M2.5 feedthrough capacitor. All specifications and alarm parameters are listed exclusively in the table below; no text-based descriptions of these data points are permitted outside the table.
