YILIANDUO 2.92mm to SSMP Male Female Cross-Series Precision RF Adapter | DC-40GHz 50Ω Passivated Stainless Steel Ultra-Miniature SMPM Millimeter Wave Test Connector

YILIANDUO is a professional cross-series millimeter-wave RF adapter designed to convert between standard threaded 2.92mm(K-type) female port and ultra-small push-on SSMP(SMPM/GPPO) female interface, fully calibrated for DC~40GHz full-band high-frequency testing. Constructed with passivated anti-corrosion stainless steel housing and gold-plated beryllium copper inner contact, this interconnect solves conversion challenges between conventional 2.92mm test instruments and miniaturized SSMP PCB modules, compact phased array antennas and high-density millimeter-wave components.

This cross-type adapter covers dual-market demand: B2B bulk purchase for RF component distributors, aerospace manufacturers, 5G millimeter-wave base station factories and automotive radar enterprises, and B2C university RF lab researchers, hardware R&D engineers and electronic measurement DIYers for VNA calibration and mini RF fixture setup. It’s a cost-effective alternative to high-priced imported Fairview, Pasternack cross-series adapters.

• Standard industry 50Ω characteristic impedance for all millimeter-wave RF circuits
• Max VSWR ≤1.2 across entire DC-40GHz working spectrum
• Ultra-low insertion loss ≤0.05dB to reduce high-frequency signal attenuation & waveform distortion

✅ SSMP Ultra-Miniature Push-On Structure Advantage

SSMP(SMPM/GPPO) is 35% smaller than regular SMP connector with blind-mate push-in design, fits high-density compact PCB layouts and space-limited millimeter-wave modules, ideal for modern miniaturized RF equipment trend.

✅ Integrated Full Metal EMI Shielding

Closed all-metal shielding shell suppresses external electromagnetic interference, ensures stable signal integrity under complex vibration & high-interference industrial testing environments; exclusively designed for high-frequency millimeter-wave instead of below-1GHz low-frequency wiring.
