Certified product lines of RF coaxial connectors, measurement cable assemblies, electromechanical switches, and fiber optic solutions from Radiall.
Radiall RF Coaxial Connectors (SMA, BNC, N, TNC series)
Radiall RF coaxial connectors deliver precision signal integrity across test instrumentation, radar transmitters, and telecommunication infrastructure.
Connector families including SMA, BNC, N, TNC, 7/16 DIN, and 2.92 mm support 50 Ohm and 75 Ohm characteristic impedance from DC up to 40 GHz with outstanding low VSWR performance.
Parameters: connector interface, gender (plug/jack), body style (straight/right-angle), impedance, and cable or PCB mount type.
High-Frequency Cable Assemblies: TestPro & SHF Series
Radiall TestPro high-performance test cables and SHF Ultra Low Loss microwave assemblies are engineered for laboratory test benches, automated test equipment (ATE), and airborne radar networks.
Armored with stainless steel spiral wrap, they deliver superior phase and amplitude stability under repeated flexure up to 67 GHz.
Specifications: maximum frequency (up to 20/40/67 GHz), assembly length, connector combination, and armor style.
Quick Lock Coaxial Connectors: QMA & QN Snap-on Series
Radiall QMA and QN quick-lock connectors provide a rapid snap-on replacement for threaded SMA and Type-N interfaces in cellular base stations and RF rack cabinets.
The snap-lock design allows tool-less one-handed connection, cutting installation time by 90% and enabling full 360-degree cable rotation after mating.
Criteria: series (QMA to 18 GHz or power QN to 11 GHz), body orientation (straight/right-angle), and ingress protection rating (IP67/IP68).
RAMSES Electromechanical Coaxial Microwave Switches
Radiall RAMSES coaxial electromechanical microwave switches set the industry benchmark for ATE switching matrices, radar installations, and satellite payloads.
The patented modular actuator architecture delivers unmatched operating lifetimes exceeding 10 million cycles with isolation over 80 dB up to 50 GHz.
Configuration: switch topology (SPDT, DPDT, SP4T, SP6T), actuator mode (Failsafe/Latching), coil voltage (12/24/28 Vdc), and TTL logic.
Radiall passive microwave components comprise precision coaxial fixed attenuators, matched RF terminations, directional couplers, and power dividers.
Designed for operations from DC up to 50 GHz with power dissipation from 1 W to 100 W, they ensure impedance matching and accurate signal level calibration.
Selection: attenuation value (1–30 dB), RF power rating (W), frequency range (GHz), and connector interface (SMA, N, 2.92 mm).
Radiall optical interconnect solutions provide high-bandwidth avionic data communications resistant to severe electromagnetic interference.
LuxCis ceramic optical termini (ARINC 801 standard) and D-Lightsys surface-mount optical transceivers deliver channels up to 10–25 Gbps under severe aircraft vibration and temperature extremes.
Options: fiber core (Singlemode 9/125 or Multimode 50/125), polish type (PC/APC), and D-Lightsys transceiver channel count.
Modular Multipin Avionics Connectors: EPX (EN 4644) & Quickfusio
Radiall EPX Series (EN 4644 standard) and ultra-lightweight Quickfusio rectangular modular connectors are purpose-built for avionic bays and airborne rack packaging.
Their modular design consolidates power, discrete signals, RF coax, and LuxCis optical lines within lightweight aluminum or plated-composite shells.
Specification: shell size (EPXA / EPXB), insert arrangement (signal, Quadrax, RF coax, optical), and shell material (aluminum/composite).
Microwave System Selection & Sizing
Application engineers assist in calculating insertion losses, frequency ranges, and impedance matching to select ideal connectors, cable assemblies, and switches for ATE and radar systems.
Replacement Interconnects & Assemblies
We provide continuous deliveries of original SMA, BNC, N-type connectors, SMP adapters, QMA quick-locks, TestPro laboratory cables, and fixed coaxial attenuators.
How to identify Radiall connector part numbers and coding
Radiall part numbers follow a structured 10-digit numeric coding convention (such as R125075000 or R161753000) encoding product line, mechanical shell geometry, mounting technology, characteristic impedance, and surface plating.
Initial digits denote the connector series: R125 for 50 Ohm straight and right-angle SMA connectors, R141/R142 for 50 Ohm and 75 Ohm BNC bayonet interfaces, R161 for Type-N microwave connectors, R222 for subminiature SMP interconnects, and R573 for multi-throw SP6T coaxial microwave switches.
To ensure exact replacement matching, copy the full manufacturer part number from the laser engraving on the metal housing, packaging label, or system installation schematics.
Precision TestPro cable assemblies for measurement laboratories
Radiall TestPro high-performance RF cable assemblies are specifically designed for metrology laboratories, vector network analyzers (VNA), and critical microwave test benches.
The engineering construction combines minimal insertion loss with outstanding phase and amplitude stability under continuous flexing and twisting.
Heavy-duty stainless steel spiral armoring shields the silver-plated center conductor and low-loss PTFE dielectric from accidental crushing or shop-floor impact.
Each cable assembly undergoes 100% factory verification testing with an individual serialized test certificate documenting VSWR, insertion loss, and phase tracking across frequencies up to 20, 40, or 67 GHz.
Packaging dense multi-board microwave subassemblies inherently introduces mechanical tolerance stack-ups regarding board spacing and axial alignment. Traditional rigid RF connectors experience excessive mechanical stress and premature fatigue in such environments.
Radiall Board-to-Board solutions overcome this challenge using floating bullet adapters that bridge receptacles across adjacent boards. 6 mm and angular tilt up to 4 degrees while preserving 50 Ohm impedance matching.
Three retention options (Full Detent, Limited Detent, and Smooth Bore) allow flexible staging for high-vibration aerospace or modular drawer architectures.
Quick lock QMA and QN connections: cutting installation labor
Standard threaded SMA and Type-N connectors require manual torque wrench tightening with strict calibration, an arduous task within crowded equipment cabinets containing dozens of closely packed ports.
Radiall QMA and QN snap-lock connectors click securely into place with simple finger pressure, providing an audible snap confirming full latch engagement. Connection time per port decreases from 30–40 seconds down to 2–3 seconds.
Once fully mated, the connector body rotates freely through 360 degrees, allowing clean cable routing and eliminating damaging torsional stress on semi-rigid or flexible cable jackets.
Reliability of RAMSES electromechanical coaxial RF switches
Radiall RAMSES (Radiall Modular System for Electromechanical Switches) technology is recognized as the global benchmark for switching reliability in aerospace, automated test equipment (ATE), and satellite communications.
The patented frictionless actuator design and precision gold-plated contact assemblies deliver guaranteed lifetimes exceeding 10 million switching cycles without RF degradation.
Control electronics options include internal TTL logic drivers, position telemetry indicator circuits, failsafe normally-closed configurations, and energy-efficient latching actuators designed for low power consumption.
In radar networks and RF transmission chains, precise power calibration and amplifier protection against reflected power mismatches are vital. 3 dB.
For high-power radio transmitters, conduction-cooled radiator terminations handling 50 to 100 Watts continuous RF power with Type-N and 7/16 DIN interfaces dissipate heat effectively across wide ambient temperature envelopes.
Modern commercial and defense aircraft rely on optical transmission backbones to handle high-bandwidth radar, sensor, and video streams free from lightning electromagnetic pulse (EMP) interference.
25 mm ceramic ferrules comply with the ARINC 801 avionics specification, fitting into MIL-DTL-38999 circular and EPX rectangular shells.
Complementing these termini, D-Lightsys surface-mount optical transceivers mount directly beside host processors, enabling multichannel data throughput up to 10–25 Gbps per channel with ultra-low weight and space consumption.
