The 145-0701-601 is an MK (2.92mm) jack assembly featuring a 2-hole flange design with gold-plated stainless steel body and insert, combined with a gold-plated beryllium copper center contact. It is designed for high-frequency RF applications with a 50-ohm impedance and operates across a frequency range of 0 to 40.0 GHz, supporting a maximum working voltage of 335 VRMS at sea level and a dielectric withstanding voltage of 1000 VRMS minimum. The connector exhibits excellent electrical performance with a typical VSWR of 1.22 maximum, RF leakage of -90 dB minimum at 2.5 GHz, and contact resistance of 6.0 milliohm maximum for the center contact. Operating over a temperature range of -65°C to 125°C and meeting MIL-STD-202 environmental standards for corrosion, shock, vibration, and moisture resistance, this connector is ideal for demanding aerospace, military, and telecommunications applications requiring reliable high-frequency signal transmission.
