Additional Details:

The SM4085 typically operates over a frequency range from DC to 3 GHz. The insertion loss is typically less than 0.5 dB. It has a surge current capability of up to 20 kA. The VSWR (Voltage Standing Wave Ratio) is typically less than 1.3:1. The connectors are typically SMA (SubMiniature version A) connectors, providing a reliable and secure connection. The operating temperature range is typically from -40°C to +85°C. The surge protector is designed to be bi-directional, meaning it can protect equipment from surges coming from either direction. The GDT technology provides a high level of protection against voltage surges by diverting excess current to ground. The compact design allows for easy installation in various applications. The housing is typically made of durable metal to provide shielding and protection against environmental factors.
