Overview
The SMB interface features a snap-on coupling mechanism and is available in 50 ohm configurations. It meets the requirements of MIL-C-39012 and complies with MIL-STD-348 standards. SMB connectors provide broadband performance with low reflection from DC to 4 GHz, with extended capability up to 10 GHz for application vehicle radar (24 GHz, 77 GHz for ADAS),cable TV distribution and headend systems . They are offered in various materials, including die-cast options in non-critical areas, delivering a reliable yet cost-effective solution.
Features
Available with various plating options, including nickel, gold, and tin-lead.
Snap-on mating enables quick connection and disconnection, reducing installation time.
SMB PCB slide-on plugs and jacks allow easy board-to-board mounting with minimal insertion force.

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.

Are RF connectors weatherproof?
Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.
What’s the difference between male and female RF connectors?
Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.
What is VSWR, and why does it matter?
VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.
What are typical applications of RF connectors?
Telecom (5G, LTE, satellite) Aerospace & defense (radar, avionics, secure comms) Test & measurement (network/spectrum analyzers) Broadcast & video distribution Automotive radar and IoT devices Medical imaging & equipment
