SMA Series
Aliner SMA connectors are precision connectors for microwave application up to 18 GHz and higher. The high mechanical strength, high durability and low VSWR indicate the characters. Together with semi-rigid cable, hi- grade lines can be installed. SMA receptacles (launchers) are used to provide transition to coax from stripline or microstrip on PCB.
