Product Overview
N-type PCB Connectors mount directly to a printed circuit board, providing an N-type RF interface at the board level without requiring a separate cable pigtail from the board to a panel-mount connector. In equipment where the PCB is positioned close to the panel wall—as is common in compact module designs—the N-type PCB connector allows the RF port to exit directly from the board edge to the equipment exterior, eliminating a lossy and mechanically complex cable transition.
The N-type PCB connector occupies a niche distinct from SMA PCB connectors (smaller body, higher frequency but lower power) and from TNC PCB connectors (similar size but 50Ω only). N-type PCB connectors are specified when the application requires the N-type's 50Ω or 75Ω impedance options, its greater power handling capacity, and its weatherproofed, field-proven connector interface—while still requiring board-level integration.
Key Features
Through-hole solder mount (vertical and right-angle) and surface-mount (SMT, reflow-compatible) PCB attachment options.
Right-angle (edge-launch) versions position the N-type mating interface at the PCB edge, aligning naturally with the equipment panel for direct panel-exit cable connections.
50Ω and 75Ω versions within the same PCB mount body series; the center pin and dielectric geometry are the only differences between impedance versions.
Multiple grounding legs on the connector body provide low-inductance PCB ground plane connection, maintaining controlled impedance through the board-level transition.
Operating frequency to 11 GHz (50Ω version); the board-launch geometry and PCB stackup design determine the practical upper frequency limit achievable in the assembled configuration.
RoHS-compliant solder-compatible plating; lead-free reflow process compatible at standard J-STD-001 lead-free profiles (peak 260°C).
Competitive Advantages
Jingcheng offers N-type PCB connectors in both 50Ω and 75Ω within a unified catalogue—a combination rarely available from a single source. This simplifies the design-in process for equipment that uses N-type PCB connectors across both impedance domains in the same product (e.g., a broadcast receiver card with 75Ω input and 50Ω local oscillator reference ports).
PCB footprint drawings and STEP 3D models for standard N-type PCB connector variants are available for direct import into common EDA tools (Altium, OrCAD, KiCad), reducing the layout engineering time required for new board designs incorporating N-type PCB connectors.
High-volume production experience with N-type connectors across the full series (semi-rigid, bulkhead, flexible, PCB) means Jingcheng's manufacturing process for N-type PCB connectors draws on a deep pool of dimensional and process knowledge, resulting in consistent quality across production lots.
Typical Applications
Base station module PCBs with direct N-type antenna port access
Broadcast receiver and transmitter module RF input/output interface boards
Satellite ground terminal downconverter and upconverter module PCBs
CATV amplifier module PCBs with N-type signal input/output
High-power RF amplifier module PCBs requiring N-type load port interface
FAQ
Q: What are the PCB layout requirements around an N-type PCB connector footprint?
A: Key PCB layout requirements include: (1) a ground plane clearance keepout beneath the connector dielectric section to prevent unintended capacitive coupling; (2) a dense via fence connecting the top and bottom ground planes within 2 mm of the connector footprint edge; (3) a 50Ω (or 75Ω) controlled-impedance trace from the center pin pad to the first RF component, with trace width calculated for the specific PCB stackup. Jingcheng's application engineers can review your PCB layout and identify potential impedance discontinuity issues before board fabrication.
Q: Is a right-angle SMT version of the N-type PCB connector available?
A: Right-angle through-hole N-type PCB connectors are standard catalogue items. Right-angle SMT versions are available as configured specials for automated production environments where through-hole connector processing is not compatible with the board assembly line. Please specify mounting style, impedance, and PCB thickness when requesting an SMT right-angle version.
Q: How does the N-type PCB connector power handling compare to the cable-terminated N-type versions?
A: PCB mount N-type connectors have lower power handling than cable-terminated versions because the PCB trace, solder joint thermal resistance, and surrounding PCB material impose additional thermal constraints on the connector. For high-power applications (>50W CW), the PCB thermal design must be reviewed alongside the connector specification. Contact Jingcheng's application engineering team for power derating guidance specific to your PCB stackup and thermal environment.
Q: Can N-type PCB connectors be used in outdoor PCB assemblies with conformal coating?
A: N-type PCB connectors can be used in conformally coated assemblies with selective masking of the mating interface surfaces. Full immersion coating is not compatible with the N-type threaded coupling interface. For outdoor PCB assemblies requiring full environmental sealing, a potted connector with defined PCB-side interface geometry is an alternative approach—contact our engineering team for guidance.
