SIPU RF Technology's SMP Female to Female Adapter 40GHz (Model: SIPU-SMP-KK1) delivers enterprise-grade performance for high-density RF applications. This precision adapter operates across DC–40 GHz with a characteristic impedance of 50Ω and maintains VSWR ≤ 1.5 throughout its frequency range. Engineered with beryllium bronze gold-plated contacts and PTFE dielectric, it supports 500 mating cycles while providing both axial and radial misalignment compensation.
The adapter achieves insertion loss of ≤0.07√F(GHz)dB and operates reliably across -65℃ to +125℃. With dielectric withstanding voltage of 500V and insulation resistance ≥ 5,000 MΩ, this straight-orientation female-to-female connector serves mission-critical applications in aerospace, 5G infrastructure, and automated test equipment where signal integrity cannot be compromised.

Your system demands reliability under challenging conditions. This SMP Female to Female Adapter 40GHz addresses alignment challenges inherent in high-density installations.
The push-on design eliminates threaded coupling requirements, reducing your installation time significantly. Misalignment compensation capability ensures consistent electrical performance even when mechanical tolerances vary across assembly batches.
Gold-plated beryllium bronze contacts deliver excellent conductivity while withstanding repeated connections. The PTFE dielectric maintains stable electrical characteristics across temperature extremes, ensuring your signal integrity remains uncompromised in demanding environments.
This adapter excels in space-constrained layouts where traditional connectors cannot fit. You gain the flexibility needed for modular architectures without sacrificing RF performance at frequencies approaching 40GHz.
Aerospace and Defense Systems: In phased array antennas and radar modules, this adapter enables blind-mating between PCB layers while compensating for thermal expansion. Multi-channel systems benefit from the compact footprint and reliable signal transmission.
5G and Advanced Communications Infrastructure: Ground station transceivers and high-speed digital backplanes require stable phase performance at millimeter-wave frequencies. The adapter maintains signal integrity critical for data throughput in next-generation networks.
Automated Test Equipment: Semiconductor testing environments demand connectors that withstand thousands of cycles. You can integrate this adapter into test fixtures for quick-disconnect interfaces that maintain low VSWR under vibration conditions.
Research laboratories and measurement systems also benefit from the precision engineering. Any application requiring repeatable connections at high frequencies will find value in this solution.

SIPU implements rigorous quality verification for every production batch. Each adapter undergoes dielectric withstanding voltage testing and insulation resistance measurement using specialized test instruments.

Plating thickness and adhesion receive batch-level inspection to ensure consistent contact performance. Your order meets RoHS environmental compliance standards, verified through batch testing protocols.
The manufacturing process includes precision dimensional verification. Contact resistance measurements confirm that center and outer conductors meet specified thresholds before shipment.
These quality measures ensure you receive adapters with predictable performance characteristics. Structural design guarantees VSWR and insertion loss specifications without requiring per-unit network analysis.

Q: What misalignment can this adapter compensate for?
A: The design accommodates typical manufacturing tolerances in board-to-board assemblies. Both axial and radial misalignment compensation capabilities make it suitable for modular system integration.
Q: How does operating temperature affect performance?
A: The adapter maintains electrical specifications across its full -65℃ to +125℃ range. PTFE dielectric and gold-plated contacts ensure stable performance under thermal cycling.
Q: What is the expected service life?
A: You can expect 500 mating cycles minimum. Actual lifespan depends on your application's mechanical stress factors and environmental conditions.
Q: Does this adapter require special installation tools?
A: The push-on interface allows hand installation in most cases. For high-density arrays, you may find removal tools helpful during maintenance to prevent contact damage.
Q: Can I use this in moisture-prone environments?
A: While the adapter functions across wide temperature ranges, you should evaluate your specific environmental conditions. Contact our engineering team for application-specific guidance.
