Board-to-Board

Amphenol RF’s board‑to‑board connectors maintain reliable RF performance across challenging alignments and tight spaces. With proprietary and industry‑standard designs offering generous float, high frequencies and seamless blind‑mate capability, these connectors adapt effortlessly to demanding application requirements.


Amphenol RF’s board‑to‑board offerings—including AFI, HD‑AFI, HD‑EFI, SMP, SMPM and PSMP series—are tailored for compact, high‑performance RF interconnects. AFI and HD‑AFI ensure excellent signal stability through generous radial and axial float, making them ideal for systems requiring tolerance to misalignment up to 18 GHz. Meanwhile, SMP and SMPM models deliver ultra‑high frequency performance (up to and beyond 65 GHz), and the P‑SMP series supports high‑power applications (over 200 W at 2.2 GHz), offering robust solutions from broadband to power‑intensive systems.

These precision-engineered connectors are ideal for applications demanding compact layouts, simplified assembly and dependable connectivity in confined spaces. Whether enabling multi‑port blind‑mate designs, facilitating dense PCB stacking, or supporting high‑frequency/misalignment‑tolerant architectures in telecom, aerospace, or measurement systems, Amphenol RF board‑to‑board connectors ensure signal integrity, streamlined installation and space efficiency in advanced electronic designs.
