The 925-106A-51S is an SMPM bullet adapter designed for high-frequency coaxial interconnect applications in the DC to 65 GHz frequency range. This micro-miniature adapter features a floating bullet design that compensates for both radial and axial misalignment between mated pairs, enabling reliable blind-mate and board-to-board connections. The adapter has a bullet length of 0.210" (5.33 mm) and requires a minimum PCB spacing of 0.341" (8.65 mm), making it suitable for compact, space-constrained designs. With 50 O impedance, low insertion loss, and excellent RF performance characteristics including return loss specifications up to 40 GHz, this adapter is ideal for miniaturized high-frequency applications such as antennas, wireless systems, military equipment, and instrumentation requiring secure engagement and precise signal transmission.
