Stainless Steel BMA Female 4-hole Flange RF Coaxial Connector
The BMA series connectors, crafted to meet the IEC1169-33
standards, incorporate a newly designed spring plate mechanism that
ensures steadfast electrical connections and superior performance
characteristics. A key benefit of these connectors is their dual
ability to float both axially and radially, alongside a compact
footprint and lightweight composition, which makes them
particularly suited for blind mate applications in chassis and
cabinetry. Widely adopted in modular connector systems for such
enclosures, the BMA series offers compatibility with international
equivalents, enabling swift engagement and disengagement. They are
frequently utilized in linking coaxial cables within radio
communication equipment and sophisticated instruments.

Features:
1. Excellent mechanical and electrical performance: it has good
mechanical strength and stability, and can withstand a certain
degree of physical stress and environmental changes. At the same
time, its excellent electrical properties, such as high insulation
resistance, dielectric withstand voltage, low voltage VSWR, etc.,
can effectively ensure the transmission quality of high-frequency
signals.
2. Convenient docking: the unique structural design makes the
connector in the case of not fully aligned can also be through the
pressure of the plug into the jack to achieve mating, and further
through the unique structural design to achieve a reliable
connection, easy and fast operation, improve the efficiency of
installation and maintenance.
3. Wide range of application frequency: According to different
designs and models, the operating frequency of BMA connectors can
cover a wide range, from DC to tens of gigahertz, which can meet
the needs of RF signal transmission in different frequency bands.
Application:
1. Radar System
Phased Array Radar: In phased array radar, a large number of RF
coaxial connectors are needed to connect the antenna array unit,
phase shifter, feed network, etc. With its miniaturization and high
performance, BMA female microstrip RF coaxial connectors can meet
the high requirements of phased array radar on connectors to ensure
the high precision and reliability of the radar system.
Meteorological radar: meteorological radar is used to monitor
weather changes and meteorological phenomena, and its RF part
requires the use of RF coaxial connectors to connect transmitters,
antennas, receivers and other equipment.BMA female microstrip RF
coaxial connectors can provide stable signal transmission to ensure
the accuracy and reliability of meteorological radar.
2. Electronic Countermeasures System
Electronic warfare equipment: in electronic warfare equipment, such
as jammer, reconnaissance aircraft, etc., need to use RF coaxial
connectors to connect a variety of RF modules and antennas.BMA
female microstrip RF coaxial connectors can provide good electrical
performance and anti-jamming ability, to meet the electronic
warfare equipment in the complex electromagnetic environment
requirements.
