3.5mm RF Coaxial Connector ---ZOMWAVE

In the mid-1960s, the U.S. Department of Commerce established a Joint Industrial Research Council (JIRC) for the standardization of small precision coaxial connectors. After hard work, a civilian product standard was proposed in 1972. The size of the air transmission line was reduced to 3.5mm. The frequency under the modeless working state is extended to 36GHz. Later, a 3.5mm mandarin duck connector (with the same header) that matched it was introduced. However, due to its high precision and high price, it hinders its widespread use as a general-purpose connector. Due to the needs of the situation, companies such as ZOMWAVE have developed a high-precision, relatively cheap 3.5mm coaxial RF connector. The matching space is filled with air medium. The inner conductor socket adopts a slotless structure. A slotless protective sleeve is added to the outside of the hole. The rated operating frequency reaches 33GHz. It chooses a sufficiently large distance between the two insulators, 0.50 inch (12.27mm), which is 3.5 times of D. The 3.5mm coaxial RF connector is compatible with SMA and can be connected without damage. Within the working frequency range of SMA, the voltage standing wave ratio of 3.5mm connector is similar to that of SMA. The 3.5mm coaxial RF connector was originally designed as a low-cost alternative to SMA, but it failed to form a batch in time to achieve the purpose of reducing costs in advance. As a result, the price of the 3.5mm coaxial RF connector was high. This is the reason why 3.5mm coaxial connectors failed to replace SMA. The 3.5mm coaxial connector is especially suitable for testing equipment due to its precision and good wear resistance.
