The SMA-JP-1 is a 50 Ω coaxial surge protective device (SPD) with SMA-type (P-J) connectors, designed for microwave wireless communication devices. It covers a frequency range from DC to 3 GHz with a VSWR of 1.2 or less and an insertion loss of 0.3 dB or less, and supports a permissible power of 10 W. Compliant with IEC 61643-21 (Category C2/D1) and RoHS, it withstands impulse currents of 5 kA (8/20 µs) and 2.5 kA (10/350 µs), with a voltage protection level of 700 V or less and a DC sparkover voltage of 120 V or more, offering reliable protection for compact RF equipment without degrading signal quality.
