SR-047-SP is the ultimate 0.047" (1.19mm) 50-ohm semi-rigid coaxial cable for mmWave/5G module designers, radar T/R module engineers, and precision RF test fixture builders who need the tightest possible routing in high-density layouts while achieving 20-30% lower insertion loss than standard SR-047 semi-rigid cable at 6-18+ GHz. RF hardware teams at communication OEMs, defense contractors, and test equipment manufacturers choose SR-047-SP when every millimeter of board space counts but signal integrity cannot be compromised. The silver-plated copper outer conductor delivers superior skin effect performance, while identical mechanical dimensions ensure seamless integration into existing mmWave front-ends, phased array PCBs, and VNA calibration fixtures.
Silver-plated copper outer conductor – 20-30% lower RF loss vs tinned SR-047 at mmWave frequencies
True 0.047" miniature diameter – Maximum density for 5G/mmWave modules and radar T/R modules
±1.5Ω 50-ohm impedance control – VSWR <1.2:1 across 18+ GHz for phase-critical applications
>100 dB shielding effectiveness – Zero crosstalk in multi-channel mmWave front-ends
OEM/ODM manufacturing – Low MOQ (5+ pcs) for RF prototyping and pilot production
Perfect SR-047 mechanical match – Drop-in upgrade for existing mmWave/test fixture designs

5G/mmWave front-end modules – MMIC-to-antenna interconnects in compact phased arrays
Radar T/R modules – Phase-matched links in AESA and mechanical scan arrays
VNA calibration fixtures – Precision adapters, torque wrenches, phase standards
Test equipment internal paths – Spectrum analyzers, signal generators, production test jigs
High-density PCBA routing – Low MOQ custom pre-formed assemblies from your RF layout files
Q: Why do mmWave engineers prefer SR-047-SP over standard SR-047 semi-rigid cable?
A: Silver-plated copper conductor cuts 20-30% insertion loss at 6-18 GHz through superior skin effect performance—critical for maintaining SNR in dense 5G/radar modules while keeping identical 0.047" mechanical specs.
Q: Can RF OEMs get custom assemblies with low MOQ?
A: Yes – MOQ starts at 5 assemblies. Custom impedance (40-75Ω), pre-formed shapes from STEP/IGES files, phase-matched sets, full test data (VSWR/IL plots) for mmWave qualification.
Q: What are typical lead times for 5G/radar prototypes?
A: Stock lengths ship same/next day. Custom mmWave assemblies: 5-7 business days from RF drawing approval. Production scaling for 100+ units: 2-3 weeks.
Q: Does SR-047-SP fit existing 0.047" semi-rigid cable designs?
A: Perfect drop-in replacement – identical OD, minimum bend radius, connector pin gauge, and mechanical tolerances used in 5G/radar/test fixtures.
Q: What RF test data ships with each mmWave assembly?
A: Full VSWR plots (DC-18+ GHz), insertion loss verification, phase stability data. Custom qualification available: TDR, PIM testing, thermal/vibration per aerospace standards.
