Product Overview: EZ-195-SM-X SMA Plug Crimp Connector from Amphenol Times Microwave Systems
The EZ-195-SM-X SMA plug crimp connector, a precision component from Amphenol Times Microwave Systems, is optimized for integration with LMR-195 coaxial cables. This device exemplifies the engineering focus on uncompromising signal integrity and mechanical robustness within RF interconnects. Drawing from the SMA interface standard, the connector maintains a reliable impedance match at 50 ohms, which is critical in minimizing reflection losses and standing wave ratios in demanding RF chains.
Hardware-level design enables the connector to achieve consistent performance over a broad frequency range, routinely supporting applications up to 6 GHz. The internal interface, utilizing a gold-plated male pin, offers low contact resistance and sustained conductivity, while the nickel-plated brass housing grants enhanced durability and corrosion resistance under field conditions. The crimp-style attachment method not only ensures rapid termination but also delivers uniformity across large-scale installations, mitigating potential for signal degradation associated with solder joints or inconsistent terminations. Visual markers and defined ferrule dimensions further standardize assembly, which is particularly valuable in scenarios requiring batch installation and field maintenance.
Electromagnetic shielding integrity remains a key advantage, as the connector’s self-aligning shell and comprehensive 360-degree contact minimize leakage and external noise ingress. This shielding performance highlights its utility in dense RF deployments such as cellular base stations and tactical communication arrays, where cross-channel interference or microphonics could impair system reliability. Enhanced physical retention, driven by precision-machined threads and positive pin engagement, translates into resilience against vibrational and mechanical stress, which proves essential in military-grade or mobile platforms.
In deployment experience, consistent crimp results heavily depend on tool calibration and meticulous cable preparation—factor deviations as minute as a fraction of a millimeter in center conductor exposure or braid trim can induce impedance discontinuities, underscoring the significance of controlled manufacturing and thorough quality checks. It becomes apparent that, while the connector’s design streamlines implementation, operational outcomes hinge on control of upstream processes. Robust installation protocols, combined with the connector’s forgiving tolerance profile, help secure both high yield and field reliability.
A distinguishing aspect lies in the EZ-195-SM-X’s versatility, balancing rapid deployment with RF performance to bridge the gap between bench testing prototypes and scaled operational networks. In many retrofitting or expansion projects, such connectors allow legacy system integration without recalibration of terminal equipment, reducing downtime and technical risk.

Key Electrical Specifications of EZ-195-SM-X SMA Plug Crimp Connector
Key electrical parameters define the performance boundaries of the EZ-195-SM-X SMA Plug Crimp Connector within RF assemblies. At the foundational level, its 50 Ohm characteristic impedance aligns precisely with the impedance standard of most RF systems. This impedance coherence is critical—not just a theoretical ideal but a practical necessity for reducing voltage standing wave ratio (VSWR), thereby ensuring minimal reflection coefficients at interconnect points. In applied contexts, such matching eliminates signal degradation and supports stable, predictable network behavior even as path lengths or frequencies vary.
The connector’s broadband operation up to 6 GHz extends the design’s versatility across contemporary wireless applications. Frequencies in this range encompass dense WiFi environments, modern cellular infrastructure, GPS modules, and various broadband wireless access points. In these scenarios, phase stability and return loss become central indicators of interconnect quality. Rigorous testing has demonstrated that the EZ-195-SM-X maintains consistent VSWR performance—typically below 1.25:1 through the upper frequency ranges—ensuring insertion loss remains within design thresholds. Such results are especially important when assembling distributed antenna systems or retrofitting base stations, where connector performance often dictates deployment feasibility.
Internally, the contact system leverages robust materials and precise geometries to maximize conductivity. The minimized contact resistance directly contributes to lower insertion loss—frequently measured at well under 0.1 dB per connection, even after repeated mating cycles. Observations from field deployments confirm that mechanical robustness aids both electrical reliability and longevity in environments subject to frequent reconnections, such as test benches and modular RF platforms. Optimal crimp termination techniques further stabilize the engagement force and prevent micro-movements that might otherwise lead to intermittent conductivity failures.
Effective integration into RF networks also depends on shielding effectiveness and connector repeatability. The EZ-195-SM-X employs a metal body and smart interface design to suppress electromagnetic interference (EMI), a factor magnified in high-density deployments. Consistency in assembly becomes pivotal; slight deviations in cable preparation or crimp pressure can materially affect return loss and shielding. Experience highlights the value of standardized tooling and inspection for maintaining connector-to-connector uniformity, a theme reinforced by low field failure rates and stable signal margins observed over time in mission-critical installations.
Maintaining a stable impedance environment, minimizing signal losses, ensuring extended frequency response, and prioritizing mechanical reliability constitute the core design realities of the EZ-195-SM-X connector.

Potential Equivalent/Replacement Models for EZ-195-SM-X SMA Plug Crimp Connector
Evaluation of replacement models for the EZ-195-SM-X SMA Plug Crimp Connector requires a methodical approach anchored in standards compliance, dimensional precision, and cable compatibility. The primary concern is maintaining seamless integration with LMR-195 coaxial cable, which dictates strict requirements on connector geometry, dielectric compatibility, and termination technique. SMA plug crimp connectors selected as alternatives must exhibit 50 Ohm impedance, ensuring signal integrity and minimal return loss across extended frequency ranges—up to 6 GHz or more—necessary for broadband and RF communication applications.
Relevant connectors from reputable manufacturers, such as Amphenol, Pasternack, or Radiall, regularly provide datasheets detailing critical parameters.
