Product Details
Introduction
Hualink SMA female vertical through hole PCB connector has a 50 ohms impedance and provides a minimum frequency of DC and a maximum frequency of 26.5 GHz. This SMA connector has a brass body with gold plating and has a Beryllium Copper contact pin. The SMA Female has outer thread design with 1/4-36 UNS-2A to provide very stable connection. SMA Jack PCB RF connector can solder feet and center contact by wave solder or reflow solder way. This SMA Female was designed with very small size (small Inner Diameter of Body & small contact pin) to provide possible good impedance matching at the joint of PCB & Connectors. If need, Hualink can also provide simulation service with PCB.

FAQ
1. How to choose the RF PCB connector?
Usually, we find a suitable connector by the below parameters:
■ Your characteristic impedance is 50 ohms or 75 ohms
■ The working frequency of your system?
■ The method of installation is solder or solderless?
■ The electrical performance requirements like VSWR and IL
■ PCB layout dimensions
2. Cut-off frequency of RF connector?
3. Hualink SMA Connectors
SMA is an acronym for Subminiature version A and was developed in the 1960's. Hualink SMA series RF coaxial connectors have a working frequency from DC to 26.5 GHz and use reliable thread connection methods. They are widely used in communication, testing, automotive, satellite, radar, radio astronomy, and other fields. The medium is polytetrafluoroethylene/PTFE; the structure is simple, subminiature units that provide excellent electrical performance from DC - 26.5 GHz. The interface is compatible with 3.5 mm, 2.92 mm, SMK, K series connectors.
