1.85mm Male to 1.85mm Male High-Performance RF Test & Measurement Cable Assembly – Use CFT240H Coax

1.85mm Male to 1.85mm Male High-Performance RF Test & Measurement Cable Assembly – Built with CFT240H Coaxial Cable

The 1.85mm Male to 1.85mm Male High-Performance RF Test & Measurement Cable Assembly — model TCB185-1.85M1.85M-1M — is engineered for precision RF and microwave laboratories requiring stable and repeatable performance up to 67 GHz. This assembly is constructed using Mechanc’s CFT240H high-performance coaxial cable, a phase-stable, ultra-low-loss variation of the CFT240 Phase-Stable 67 GHz Precision Test Coaxial Cable. Both ends are terminated with rugged 1.85 mm male connectors (reference 1.85-JCFT240H-1), providing superior repeatability for high-frequency measurement systems.

Stable, Low-Loss Performance Across the 67 GHz Band

Designed for advanced microwave characterization, the TCB185-1.85M1.85M-1M supports continuous operation from DC to 67 GHz with a 1.3 typical VSWR and 6.73 dB typical insertion loss per meter. This ensures clean transmission paths for VNA calibration, broadband S-parameter measurements, and high-resolution frequency sweeps. With its controlled impedance and stable return-loss performance, the assembly delivers accurate, repeatable results for mission-critical test applications.

Phase-Stable Construction with High Mechanical Reliability

The CFT240H coaxial cable is engineered to reduce electrical drift during bending, thermal shifts, or repeated repositioning. Offering ±10° mechanical phase stability and ±0.10 dB amplitude stability, the cable maintains consistent performance even under demanding usage cycles. Its compact 2.4 mm outer diameter and 24 mm minimum bend radius support efficient routing in dense test setups, while a 2,000-cycle bend life ensures long-term reliability in automated or repetitive measurement environments.

Precision 1.85mm Connectors for Repeatable High-Frequency Testing

Each end of the assembly uses high-accuracy 1.85-JCFT240H-1 connectors designed for mating stability and low reflection at millimeter-wave frequencies. These precision interfaces ensure secure engagement for frequent VNA connections, high-power module testing, and production-line verification.

Qualified for Advanced RF & Microwave Test Environments

Each TCA-series assembly undergoes comprehensive testing for VSWR, insertion loss, phase stability, and mechanical endurance. The TCB185-1.85M1.85M-1M operates across a wide -55 °C to +165 °C temperature range and meets REACH and RoHS requirements, ensuring long-term reliability for high-performance RF and microwave measurement systems.
