SIPU RF Technology’s SIPU-SMP-KK7 is a precise SMP Female to SMP Female Adapter for demanding microwave applications up to 40GHz. This subminiature push-on interconnect has a 50Ω characteristic impedance with excellent electrical performance: VSWR ≤ 1.5 and insertion loss ≤ 0.07√F(GHz) dB from DC to 40 GHz.
The adapter is made from quality beryllium bronze and precision gold plated and is rated for ≥500 mating cycles with reliable performance from -65℃ to +125℃. With a straight-orientation design of 8.2 mm, these connectors provide dielectric withstanding voltage of 500V and insulation resistance ≥5,000 MΩ to ensure reliable performance in high density board-to-board and blind-mate connections where space optimisation and signal integrity are paramount.
The interconnect component provides a precise coupling bridge between two SMP male interfaces. The adapter facilitates modular assembly for the miniaturised microwave systems when direct connector-to-connector mating is not feasible.
The straight through female to female option tackles mechanical tolerance problems in multi-layer PCB designs. It can compensate for small misalignments and maintains signal integrity.
This SMP Female to SMP Female Adapter is specified by engineers for applications that require tool-less assembly and disassembly. Push-on interface reduces threading, saving installation time in high density arrays.

The SIPU-SMP-KK7 utilizes beryllium bronze alloy for both center and outer conductors. This material choice delivers exceptional spring characteristics and mechanical resilience under repeated connection cycles.
The gold plating is precisely applied to provide oxidation resistance and minimal contact resistance over the life time of the adapter. Consistent electrical conductivity even in harsh situations is guaranteed by the surface treatment.
The dielectric substance of PTFE has steady electrical characteristics throughout the complete temperature range. This mix of materials allows for prolonged operation in extreme circumstances while maintaining signal integrity.
The robust construction withstands mechanical stress from blind-mate applications. Your high-frequency assemblies benefit from reduced maintenance requirements and extended operational lifespan.
SIPU implements rigorous quality verification protocols for every production batch. Dielectric withstanding voltage and insulation resistance testing utilize precision measurement equipment to verify electrical safety margins.

Each batch undergoes plating thickness verification and adhesion testing. These inspections ensure the gold layer meets durability requirements for your specified mating cycle count.
RoHS environmental compliance testing is performed on every production lot. This verification guarantees the adapter meets international environmental regulations for global deployment.
The manufacturing process includes dimensional inspection to maintain tight tolerances. You receive consistent mechanical fit and electrical performance across all units in your order.
