BMA Male 2-Hole Flange Mount Microstrip Connector

BMA Male 2-Hole Flange Mount Microstrip Connector 

SIPU RF Technology BMA Male 2-Hole Flange Mount Microstrip Connector (Model: SIPU-BMA-JFD1) provides precision designed blind-mate performance for rack-and-panel RF systems running from DC to 18 GHz. The connection is manufactured to military-grade specifications and supported by more than 25 years of RF experience, and has a typical impedance of 50Ω, low VSWR of ≤1.15+0.012F(GHz) and low insertion loss of ≤0.08√F(GHz)dB. Gold plated brass structure assures center contact resistance ≤3.0mΩ and outside contact resistance ≤2.0mΩ. PTFE dielectric enables steady performance from -65℃ to +125℃. It satisfies your high density modular assembly and repeatable connection demands with ≥ 500 mating cycles and 1,000V dielectric withstanding voltage.

Key Features and Advantages

The blind-mate interface enables quick engagement without manual threading, significantly reducing assembly time in complex multi-port configurations. Your microstrip PCB mount design minimizes signal path transitions, preserving RF integrity in high-frequency applications.

The 2-hole flange mount provides robust mechanical anchoring with simplified alignment compared to conventional threaded connectors. This structure delivers excellent vibration resistance, critical for aerospace and defense platforms.

Compact footprint optimization allows you to achieve higher connector density on PCB layouts. The straight orientation and male interface configuration suit modular RF systems where space constraints demand efficient packaging.

Precision machining combined with strict quality control ensures consistent electrical performance across production batches. Gold plating on both center and outer conductors provides superior conductivity and long-term corrosion resistance.

Primary Applications

Phased Array Radar Systems: The BMA Male 2-Hole Flange Mount Microstrip Connector enables rapid swapping of Transmit/Receive modules in high-density antenna arrays. Multiple RF paths align simultaneously without individual connector threading, reducing maintenance downtime.

Modular Test Instrumentation: In PXI and VXI backplanes, this connector facilitates reliable interfaces between high-speed microstrip PCB boards and system chassis. It maintains signal integrity under thermal expansion and contraction cycles.

Aerospace and Satellite Communications: The 2-hole flange provides mechanical stability against high-vibration profiles during launch and flight operations. The microstrip transition ensures a low-profile footprint, optimizing Size, Weight, and Power (SWaP) budgets on flight-grade RF boards.

RF Communication Systems: Your system benefits from stable signal transmission in microwave test equipment and communications infrastructure requiring precise, repeatable connections.

Quality Control Process

SIPU implements comprehensive inspection protocols to ensure field reliability. Each production batch undergoes dimensional verification using Coordinate Measuring Machines (CMM) to confirm flange hole spacing and pin protrusion accuracy.

Plating quality receives particular attention through regular testing. We verify gold plating thickness and bonding strength for every batch, ensuring durability against fretting corrosion. RoHS environmental compliance testing is performed on each production lot.

Electrical performance validation includes insulation and dielectric withstanding voltage testing using specialized equipment. The structural design guarantees VSWR and insertion loss performance, with 100% testing applied only to loads and cable assemblies according to industry best practices.

Mechanical endurance testing validates spring-finger tension and mating cycle durability. Environmental stress screening subjects components to temperature cycling, confirming that microstrip-to-connector transitions remain stable under extreme gradients.
