The SMP-MSPR-FL-1 is an SMA female flange test probe for SMP male connectors, engineered to interface with SMP jack connectors per MIL-STD-348 specifications. This connector features a 50-ohm impedance with a frequency range of DC to 15 GHz, supporting high-speed signal transmission with a maximum VSWR of 1.05 + 0.045 F (GHz). The probe is constructed from brass with gold plating on the SMP body, beryllium copper gold-plated contacts, and PTFE insulators, with a music wire zinc-plated spring mechanism. Mechanically, it offers 100,000 cycles minimum durability on the SMP plug side, operates across a temperature range of -40°C to +80°C, and features a working compression distance of 3.231 mm with a relaxed length of 39.75 mm. This test probe is ideal for RF/microwave measurement applications, laboratory testing, and high-frequency signal verification where reliable, repeatable connections are essential.
