63551-3

The 63551-3 by TE Connectivity AMP Connectors establishes new performance standards in Terminals - Magnetic Wire Connectors for test and measurement equipment. Precision-engineered with air dielectric technology, this connector maintains VSWR <1.05 up to 67GHz, making it indispensable for 5G NR device testing and millimeter-wave research.The 300 configuration features precision APC-7 interface compatibility with 0.1dB repeatability. When compared to conventional SMA connectors, this design demonstrates 10x better phase stability during thermal cycling.Featuring Poke-In Terminal technology, the contacts use beryllium copper with proprietary surface treatment that minimizes passive intermodulation (PIM). Testing shows <-170dBc PIM performance even after 5000 mating cycles.Manufactured to 2 tolerances, the connector achieves /20 phase matching at 40GHz. The ultra-precision machining ensures consistent performance across calibration laboratory environments.Optimized for IDC in metrology applications, the connector features torque-limiting interfaces that prevent over-tightening. This design maintains NIST-traceable accuracy through 10,000 connection cycles.Compatible with 23-27 AWG semi-rigid cables, the connector supports both fundamental mode propagation and higher-order mode studies. The gas-tight interface prevents moisture ingress in environmental chambers.
