Features:
1. Small size and light weight: As a miniaturized product of BMA
series, SBMA connector has smaller size and lighter weight, which
is suitable for use in equipment with limited space, and is
conducive to the miniaturization and lightweight design of
equipment.
2. High installation density: its miniaturization makes it possible
to install more connectors per unit area, which improves the
installation density and meets the demand for high-density
integration of modern electronic equipment.
3. Reliable connection: the blind plug structure design, without
the need for complex alignment operations in the connection, just
insert the plug into the socket to complete the connection, simple
and convenient operation, and the connection is firm and reliable,
can withstand a certain degree of vibration and shock.
4. Long mechanical life: the general mechanical life of SBMA
connectors can reach more than 500 times, and some products are
even higher, which can meet the requirements of long-term frequent
plugging and unplugging.
Application:
1. Wireless communication: In various types of wireless
communication equipment, such as base stations and mobile
terminals, SBMA connectors are used to connect antennas and RF
front-end modules to ensure stable transmission of high-frequency
signals. Due to its miniaturized design, it is able to achieve
efficient connection in limited space, which contributes to the
miniaturization and lightweighting of communication equipment.
2. Satellite communication: Satellite communication system requires
high reliability and performance of connectors, SBMA connectors are
widely used in communication equipment on satellites to guarantee
the signal transmission quality between satellites and ground
stations by virtue of its good electrical performance, high
reliability, and anti-vibration and anti-shock characteristics.
3. Data transmission: In the field of high-speed data transmission,
such as fiber-optic communications, data centers, etc., SBMA
connectors can be used to connect a variety of high-speed signal
transmission equipment to meet the needs of large-capacity,
high-rate data transmission to ensure the stability and accuracy of
data transmission.
