Rosenberger’s new RPC-1.35* precision connector series meets the growing demand for precision, high-performance RF-connections up to 90 GHz. The range addresses the expanding market for 5G, industrial sensors in the E-Band, millimeter wave sensors for self-driving vehicles, WLAN IEEE 802.11ax and 802.11ay. RPC-1.35 connectors offer a highly robust mechanical design, minimum 3000 mating cycles, high connector repeatability, and maximum return loss values – ideal for ensuring RF measurements in the E-Band without delays.

The product portfolio covers semi-rigid and flexible cable assemblies, PCB connectors, test PCBs, cable connectors, in-series and inter-series adaptors, test ports, floating and waveguide-to-coaxial adaptors as well as gauge and calibration kits.

*A working group, comprising PTB (Physikalisch Technische Bundesanstalt), Rosenberger, Rohde & Schwarz and Spinner, designed the new 1.35 mm connector to close the gap between 1.85 mm and 1.00 mm connectors. The interface standardization is in progress.


Product Portfolio

  • Interface standardization of the 1.35 mm interface is in progress for IEC (IEC 61169-65) and for IEEE (IEEE Std 287)
  • Frequency range DC to 90 GHz
  • Mating cycles ≥ 3000
  • Air dielectric with PEEK bead
  • Stainless steel or CuBe outer contact



  • Screw-on/Threaded locking mechnism, Push-pull as an option
  • "Thru male" capability, i.e. pin diameter must coincide with inner conductor of standard 0.047-inch semi-rigid cable (largest cable covering the E-Band)
  • Damage-free connection
  • Excellent return-loss values
  • Reliability and repeatability
  • The precision connector which ensures a pin gap in mated condition to avoid near field effects from impairing connector repeatability
  • The precision connector which uses a common reference for all eccentricity tolerances to prevent for a tolerance chain
  • The precision connector for higher frequencies with a provision for push-pull locking
  • High-quality low budget jumper cables possible, because pin diameter is equal to center conductor of 0.047-inch semi-rigid cables
  • Can be used with the same torque wrench as most precision connectors (3.50 mm, 2.92 mm, 2.40 mm, 1.85 mm)



  • Precision measurements in high microwave applications up to 90 GHz
  • For E-band applications
