BNC Male to RP-SMA Female Jumper Cable | LMR-195 Low-Loss RF Extension for Wi-Fi 6/6E, 5G, and IoT Device Testing
Meta Description (SEO):
Precision LMR-195 cable assembly with BNC male to RP-SMA female connectors. Engineered for 50Ω wireless testing (2.4/5/6 GHz), IoT prototyping, and cellular signal validation. 40% lower loss than RG-58, UV-resistant jacket, and MIL-STD durability. Includes NIST-traceable calibration.
Purpose-Built for Wireless Device Testing & Prototyping
This LMR-195 RF jumper bridges standard test equipment (via BNC male) to RP-SMA female ports found on Wi-Fi routers, cellular modems, and IoT devices. Designed for 50Ω systems, it delivers ≤ 0.25 dB/m loss @ 2.4 GHz and VSWR ≤ 1.15:1 up to 6 GHz—critical for Wi-Fi 6E/7, 5G NR, and LoRaWAN validation. The RP-SMA female connector (reverse polarity) ensures compatibility with FCC-certified wireless hardware, while LMR-195’s low-loss design outperforms RG-58 by 40% in signal integrity. Critical: RP-SMA ≠ standard SMA—using standard SMA risks damage to antenna ports.

1. RP-SMA Female Precision
Reverse polarity matches FCC-certified wireless hardware (e.g., Wi-Fi APs, 5G CPEs) to prevent unauthorized high-gain antennas.
Critical: Standard SMA male connectors will not mate with RP-SMA female ports—this assembly avoids costly port damage.
2. LMR-195 Low-Loss Performance
40% lower loss than RG-58 at 5 GHz (0.35 dB/m vs. 0.60 dB/m), preserving signal integrity for:
Wi-Fi 6E channel bonding validation
5G NR throughput testing (100+ Mbps accuracy)
IoT sensor RSSI/SNR measurements
3. 50Ω RF Integrity for Modern Wireless
Matches impedance of Wi-Fi/cellular systems to eliminate reflections during:
EIRP (Effective Isotropic Radiated Power) calibration
MIMO antenna pattern analysis
Adjacent-channel interference testing
4. Right Angle Design (Optional)
Fits tightly behind wall-mounted APs or in compact test jigs.
Reduces strain on delicate RP-SMA ports during repeated connections.
Wi-Fi 6E/7 Validation: Testing 160 MHz channel performance, DFS compliance, and beamforming.
5G Field Testing: Connecting spectrum analyzers to cellular modems for signal quality analysis.
IoT Prototyping: Linking LoRaWAN/NB-IoT sensors to gateways during development.
Regulatory Compliance: EIRP measurements for FCC/CE certification labs.
Network Troubleshooting: Isolating antenna vs. radio faults in deployed systems.
1. RP-SMA Polarity Validation
Every unit tested with polarity verification gauge to confirm center socket alignment (no false positives).
Cross-checked against FCC ID databases for model-specific compatibility (e.g., Cisco Aironet vs. Ubiquiti).
2. Signal Integrity Testing
VSWR/loss measured to 6.5 GHz (covering Wi-Fi 7 6 GHz bands) using vector network analyzer.
Batch-tested for phase stability (critical for MIMO systems).

3. MOQ: 1 unit (stock); custom lengths require 10+ units.
4. Bulk Orders: Serialized for lab asset tracking (e.g., "Calibration ID: LAB-5G-2024").
Q1: What’s the difference between RP-SMA and standard SMA?
A: RP-SMA reverses the center contact:
Q2: Can I use this for 6 GHz Wi-Fi 6E/7 testing?
A: Yes. LMR-195 maintains ≤ 0.42 dB/m loss at 6.5 GHz, making it suitable for UNII-5–8 bands (5.925–7.125 GHz). For >100 cm lengths, consider LMR-240.
Q3: Is this cable suitable for outdoor use?
A: Limited. The standard PVC jacket is UV-resistant but not waterproof. For outdoor deployments, specify LMR-195 with flooded PE jacket (IP67 rated).
Q4: Why not use cheaper RG-58?
A: RG-58 has ~60% higher loss at 5 GHz (0.60 dB/m vs. 0.35 dB/m), distorting Wi-Fi 6E/7 signal measurements. LMR-195 is cost-effective for lab-grade accuracy.
1. Verify RP-SMA Polarity: Confirm your device uses RP-SMA female (common on Wi-Fi APs) vs. standard SMA.
2. Length vs. Frequency Tradeoff:
≤ 50 cm: Ideal for 6 GHz testing (minimal loss).
> 100 cm: Requires LMR-240 for 6 GHz applications.
3. Not for High Power: Max power handling = 30W @ 2.4 GHz (derate to 15W @ 5.8 GHz).
