Overview of SMA Series Coaxial Receptacles and In-Series Adaptors

The R125.705.701 Series SMA datasheet details high-precision coaxial receptacles and in-series adaptors designed for versatile applications. Primarily constructed from stainless steel with a passivated finish, the central contact is made from beryllium copper with a 1.3 micrometers thick gold plating over 2 micrometers nickel plate. The outer contact shares the same plating specifications, whereas the insulator is fabricated from PTFE. All dimensions provided are in millimeters.

Electrical Characteristics

These components boast an impedance of 50 ohms and can operate within the frequency range of 0 to 27 GHz. Featuring a Voltage Standing Wave Ratio (VSWR) of 1.05 + 0.005 x F(GHz) Maximum and an insertion loss of 0.03 VF(GHz) dB Maximum, they maintain RF leakage to a bare minimum. The adaptors can handle a voltage rating of 500 Veff Maximum and endure a dielectric withstanding voltage of 1000 Veff Minimum. Their insulation resistance is greater than 5000 MΩ Minimum.

Environmental Specifications

The receptacles and adaptors are designed for a broad operating temperature range from -65 to +165 degrees Celsius and maintain an atmospheric leakage rate specified as not applicable, indicating high-sealing integrity under pressured conditions.

Mechanical and Other Characteristics

Mechanical stability is ensured with a center contact retention force and axial force (both mating end and opposite end) of 27 N Minimum. Torque is kept to a minimum of 2.8 N.cm. For maintenance of the connection quality, the mating cycle is capable of at least 500 cycles. The weight specification is listed but not quantified in the excerpt provided.

The datasheet warns of potential design changes to improve product performance, indicating ongoing optimization work by RADIALL. While it doesn’t detail the assembly instructions or recommended torque values for mating panel nuts, it stipulates that users should follow specific instructions to achieve optimal performance.

For search engine optimization, this summary includes important specifications and characteristics such as materials, plating, frequency range, mechanical properties, and environmental capabilities of the SMA Series Coaxial Receptacles and In-Series Adaptors.
