Brass BMA Female 4-hole Flange High Performance RF Coaxial
Connector
The BMA series represents a blind mate connector meticulously
engineered and manufactured in adherence to the IEC1169-33
standard. Distinguished by its innovative spring plate mechanism,
it ensures dependable connectivity alongside enhanced electrical
properties. A key benefit of this connector lies in its capability
for both axial and radial floating, facilitated by minimal
clearance between each contact point and its lightweight design,
rendering it ideal for applications necessitating blind mating
within chassis enclosures.
Widely employed in modular connections for chassis cabinetry, the
BMA series boasts compatibility with international counterparts,
enabling swift engagement and disengagement procedures. These
connectors are prevalent in establishing coaxial cable links within
radio frequency equipment and sophisticated instruments,
underscoring their versatility and reliability in high-frequency
communication setups.

Features:
1. Small size: with ultra-compact blind plug and slide-in design,
compared with some other traditional RF coaxial connectors, its
size is smaller, especially suitable for use in space-limited
occasions, such as high-density integration areas in modern
communication equipment.
2. Reliable contact: can ensure good electrical connection, reduce
contact resistance, ensure the stability and accuracy of signal
transmission, reduce signal loss and reflection.
3. 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 performance, such as high insulation
resistance, strong dielectric withstand voltage, low voltage VSWR,
etc., can effectively ensure the transmission quality of
high-frequency signals.
Application:
1. Base station construction: In mobile communication base
stations, BMA female microstrip RF coaxial connectors are used to
connect various RF equipments in the base station, such as power
amplifiers, filters, antennas and so on, to ensure the stable
transmission of signals and the efficient operation of the
equipments. Its reliable electrical performance and mechanical
stability can meet the requirements of long time and high load work
in the base station.
2. Microwave communication system: In microwave communication
system, the connector can be used to connect microwave transceiver
modules, mixers, couplers and other microwave devices to realize
the transmission and processing of microwave signals.
3. Satellite communication earth station: In satellite
communication system, the BMA female microstrip RF coaxial
connector is used to connect the RF front-end devices of the earth
station, such as low-noise amplifier, up/down converter, antenna
feeder, etc., as well as other equipments related to the satellite
communication, to ensure the quality of the satellite signals
received and sent.
