The 2.4 series thread mated connectors with characteristic impedance 50Ù are used formillimeter wave applications, connecting with RF cables or microstrips. The operatingfrequency limit is up to 50GHz.These connectors can be intermated with 1.85mm (IEC 61169-32 and IEEE Std 287-2007)connectors.This sectional specification provides information and rules for preparation of detailspecification of 2.4 series R.F connectors together with the pro-forma blank detailspecification.It also prescribes mating face dimensions for high performance connectors grade 1,dimensional detail of standard test connectors grade 0, gauging information and testsselected from IEC 611
