This pigtail is the preferred solution for mission-critical RF signal routing in demanding environments:
Radar Systems: Enables stable signal transmission between radar modules and test equipment in airborne, maritime, and automotive LIDAR applications — 90° design minimizes strain on sensitive front-end components.
5G Base Stations: Connects mmWave antenna arrays to VNA and signal analyzers during FR2 (24–40 GHz) calibration and field validation.
Satellite Communications: Used in ground station RF front-ends for uplink/downlink testing with low phase noise and high return loss stability.
EMC/RF Test Labs: Ideal for connecting DUTs to spectrum analyzers, signal generators, and power meters without introducing measurement artifacts.
Defense & Aerospace: Complies with MIL-C-17 for avionics, missile guidance, and electronic warfare systems requiring vibration resistance and thermal stability.
Non-Destructive Testing (NDT): Links high-frequency ultrasonic transducers to signal conditioning units in harsh industrial environments.
Compact Wireless Modules: 90° right-angle SMB interface allows routing in confined spaces — perfect for embedded systems, UAV payloads, and IoT sensor nodes.
The 90° SMB interface reduces mechanical stress on the connection by up to 75% compared to straight configurations, while the SMA bulkhead mount ensures secure panel integration — critical for systems requiring zero signal drift under thermal cycling or vibration.
True 40GHz Bandwidth: Unlike “20GHz” cables, this assembly is tested and certified for full 40GHz operation — essential for next-gen radar and 5G FR2.
Military-Grade Construction: Silver-plated copper-clad steel conductor + solid PTFE dielectric delivers superior phase stability and low dispersion.
Bulkhead Mount Design: Threaded SMA female connector locks directly into equipment panels — eliminates strain relief failures common with cable-only assemblies.
>90 dB Shielding: 100% copper braid coverage prevents EMI ingress/egress — critical for sensitive measurement environments.
Gold-Plated Contacts: Ensures<1 mΩ contact resistance and corrosion resistance in salt-laden or high-humidity environments.
PTFE Jacket: Withstands -65°C to +165°C — ideal for engine bays, space-constrained avionics, and outdoor base stations.
100% RF Tested: Each unit undergoes full VNA calibration (S11, S21) with traceable test reports available upon request.
