Bridging High-Power RF and Miniature Electronics
This specialized RG174 coaxial cable assembly is designed to bridge the gap between high-power RF systems and high-density circuit boards. It features a rugged N-Type Male connector on one end, capable of handling high power levels and frequencies up to 11 GHz, and a compact 10-32 UNF (M5) Microdot Male Plug on the other for space-constrained applications. Perfect for converting signals from base station antennas, broadcast equipment, or radar systems to fit into miniature PCBs, this jumper ensures a reliable 50 Ohm impedance path with minimal signal degradation.

1. N-Type Connector: The Industry Standard for High Power
The N-Type connector is a threaded RF connector known for its robustness and ability to handle high power.
High Power Handling: Ideal for applications involving transmitters, antennas, and broadcast equipment where power levels exceed the capabilities of SMA or BNC connectors.
Weatherproof: The threaded interface and dielectric seal make it suitable for outdoor installations and harsh environments.
2. 10-32 UNF (M5) Microdot Interface
The 10-32 UNF thread is the industry standard for miniature RF connections.
Secure Locking: Prevents accidental disconnection in high-vibration environments (e.g., industrial machinery).
Low Profile: The Microdot head is only a few millimeters high, allowing direct mounting on crowded PCBs without obstructing nearby components.
3. RG174: The Optimal Balance
While thinner cables exist, RG174 offers the best compromise between size and performance.
Low Loss: Compared to thinner micro-coaxial cables (like RG316), RG174 offers lower attenuation per meter.
Durability: The 2.49mm outer diameter provides enough mechanical strength for repeated mating cycles without breaking.
Telecom Infrastructure: Connecting base station antennas to internal PCBs or test equipment.
Broadcast & Media: Wiring in TV and radio transmission equipment.
Radar Systems: Connecting high-power radar modules to control boards.
Industrial IoT: Connecting sensors and actuators in high-power industrial environments to compact control boards.
Precision Termination Process:
Laser Trimming: Ensures precise stripping of the jacket and dielectric without nicking the center conductor.
Solder & Crimp: The N-Type uses a precision die-cast body with a gas-tight solder connection. The Microdot utilizes a solder-cup termination for low resistance.
100% Testing: Every single cable is tested on a Vector Network Analyzer (VNA) to verify Return Loss and Insertion Loss metrics up to 11 GHz.
Traceability:
Each batch is serialized, and test data is archived to meet ISO 9001 standards, providing full traceability for your quality assurance needs.
Standard Packaging: Individually poly-bagged to prevent connector damage.
Labeling: Clear labels indicate cable type, length, and batch code.
Carton: Packed in sturdy export cartons suitable for international shipping (ISTA 3A certified).
Lead Time: Standard lead time is 7-10 working days after order confirmation.
Q1: What is the difference between 10-32 UNF and M5?
A: They are the same thing. 10-32 UNF refers to the thread specification (10 threads per inch, Unified National Fine), while M5 refers to the metric diameter (5mm). In the RF connector industry, "Microdot" usually implies the 10-32 UNF thread.
Q2: Can I get this cable with a straight Microdot instead of an angled one?
A: Yes. While the 90-degree (right-angle) Microdot is standard for PCB mounting, we offer Straight (0-degree) Microdot configurations for specific housing designs. Please specify your requirement during the inquiry.
Q3: Is RG174 suitable for outdoor use?
A: The standard PVC jacket is for indoor use. For outdoor or high-temperature environments (e.g., engine bays), we recommend the FEP (Teflon) jacketed version, which is UV resistant and rated up to 200°C.
Q4: What is the minimum order quantity (MOQ)?
A: As an OEM manufacturer, our standard MOQ is 100 pieces. However, we offer sample pricing for prototyping and testing purposes.
This N-Type to Microdot pigtail is not just a wire; it is an engineered signal path. By combining the high-power capability of N-Type with the space-saving design of Microdot technology, we deliver a product that ensures your critical RF signals arrive intact, even in the most demanding environments.
