RF Cable Male To Male

• SMA Male to Male (Plug to Plug): Both ends have a threaded 1/4-36 UNS nut and center pin
• 50-Ohm Impedance: Industry standard for RF/microwave systems (matched to most antennas, radios, and test gear)
• Threaded Coupling: Prevents accidental disconnection from vibration (ideal for drones, vehicles, outdoor installations)
• Frequency Range: DC to 18 GHz (standard), up to 26.5 GHz (precision connectors)
• Low VSWR: ≤1.2:1 through 12.4 GHz (minimizes reflected power and signal ripple)
• PTFE Dielectric (optional): Withstands high temperature (-65°C to +165°C) for avionics or engine bay routing
• Shielded Construction: Braid + foil (90+ dB isolation) eliminates external interference

1. Universal 50Ω Interconnect for Lab & Field
Wi-Fi, Bluetooth, Zigbee, LoRa, GPS, cellular, amateur radio, and test equipment all use 50Ω SMA interfaces. This single cable type replaces dozens of proprietary adapters. Benefit: Standardize your RF test bench or field kit around SMA male-to-male.

2. Vibration-Proof Connection for Drones & Vehicles
Push-on connectors (U.FL, MCX) loosen after a few flights due to propeller vibration. SMA's threaded nut locks with moderate torque (3–5 in-lb). Evidence: Used in DJI FPV air units and industrial drone telemetry where loose connectors cause failsafe.

3. Low VSWR Protects Transmitter Final Stage
A mismatched load (high VSWR) reflects power back into the amplifier, causing overheating and reduced lifespan. SMA-to-SMA cables are individually tested for return loss. Benefit: Longer life for your RF power amplifier or transceiver.

4. Semi-Rigid Option for Phase-Stable Test
For VNA (Vector Network Analyzer) calibration, a flexible cable changes phase with movement. Semi-rigid SMA male-to-male cables maintain a constant electrical length. Benefit: Repeatable S-parameter measurements without re-calibration.

• Connector Gender (both ends): SMA male (standard) or SMA female (bulkhead)
• Cable Type: RG174, RG316, LMR-100, LMR-200, semi-rigid (0.086″ or 0.141″)
• Length: 0.1m to 5m (flexible cables), 0.1m to 1m (semi-rigid)
• Orientation: Straight, right-angle (90°) on one or both ends
• Body Material: Nickel-plated brass, gold-plated, stainless steel
• Jacket Material: PVC, PTFE, LSZH
• Weatherproofing: Heat-shrink boot over the nut
• Packaging: Bulk bag, individual poly bag

• VNA (Vector Network Analyzer) test port cables: SMA male to test device
• Drone / FPV video transmitter to antenna: 5.8 GHz analog or DJI digital
• SDR (Software Defined Radio) to external antenna: RTL-SDR or HackRF dongle to a roof antenna
• GPS timing receiver to antenna: Extension from indoor receiver to outdoor antenna
• Lab equipment interconnect: Signal generator → spectrum analyzer → power sensor
• Ham radio portable setup: HT (handheld) to roll-up J-pole via SMA male

1.Carlos M., Automotive EE in California
"GPS receiver inside dashboard, antenna on roof. 3m SMA male to SMA female extension routed through firewall. The FEP jacket withstood engine heat. GPS signal strength unchanged – low insertion loss."

2.Sarah K., Ham Radio in NY
"Portable SDR setup (Hack RF). Used 1m RG316 SMA male to SMA male. The PTFE dielectric made the cable flexible enough to stuff into a go-bag. Threaded connectors survive repeated field assembly without wearing out."

3.Dave P., Lab Test Tech in Florida
"Spectrum analyzer to device under test. We use 0.5m semi-rigid SMA cables. They hold their shape once bent, giving a consistent phase length for comparison measurements. VSWR <1.1:1 up to 12 GHz."

4.Priya K., IOT Hardware Engineer IN
"LoRa gateway with external SMA antenna on a metal pole. Bought 10m LMR-200 to SMA male to N-female adapter to reach the radio. The cable loss at 868 MHz is negligible ( <0.2dB ). Threaded connector never loosened from wind vibration."
