SMP Series RF Coaxial Connectors
Brief Introduction
l
Miniature push type RF Coaxial Connectors
l
Small size, saving mounting space to the max, the operating frequency range DC ~ 40GHz
l
Excellent electrical characteristics, mechanical characteristics, and environmental characteristics
l
There are 3 kinds of Interfaces that is Full escapement, Semi escapement and Aperture. The
customer can make choice according to the different application requirements.
Advantages
SMP series RF coaxial connectors have small size and widely used in radio frequency circuit
connection between boards. It can save large mounting space to realize high density board room
connection. The working bandwidth scope is DC ~ 12.4 GHz. This series has smooth manting,
quick coupling and can connect coaxial cable and microstrip circuit to realize conversion between
coaxial system and microstrip system, etc. Clear “identification” for the attachment inplace----more reliable operation during mounting.
SMP series connector plug has three structures:
1. Full escapement structure
2. Semi escapement structure
3. Aperture structure
According to the different using environment, the user can choose plugs with different
structures. When a user does not need frequent insertion, they can use full escapement structure.
When they need many times of insertion, they can use semi escapement structure. When they
need more or need to assemble many SMP board to board connectors，they can use the aperture
structure.
SMP series connector receptacle has three structures:
1. With shielding ring and shockproof ring structure（generally used for military products）
2. With only fixed ring structure (generally used for civilian products)
3. Without shielding ring and shockproof ring structure (partial adapter)
Shielding ring can reduce radio frequency leak and the fixed ring plays the interface fixation effect
after coupling to make connector characteristics more stable. According to their different
requirements, users can make choice. Recommend to choose the receptacle with shielding ring
and shock ring structure.

Quick connect---- Convenience and time saving
Due to the use of direct push type structure during SMP plug and socket mating, it only takes 3
seconds to screw joint.

Mounting space miniaturization------ To realize high density connection
Due to the small size of SMP series FR coaxial connector, it is widely used in board to board RF
circuit connection, and can saving mounting space to realize the high density connection, the
minimum center distance is 5×5mm, the minimum board spacing is 1.1mm.

Three interface types--- Convenient for customers selection
SMP series has three interface types: full escapement, semi escapement and aperture, According
to their different requirements ,users can make a convenient choice.
