Description
Introduction
Hualink high-precision SMA End Launch connectors are designed to provide low VSWR up to 26.5 GHz for single-layer and multi-layer edge mount PCB where the signal trace is on the top layer. It's designed into 2 sections for more stable installation on PCB, solderless design of both outer contact and signal contact make it high-efficiency to connect or disconnect, which make sharing test PCB possible and save much cost.

FAQ
1. End Launch Connectors – Installation Procedure
Step 1: Mount the end launch connector on the board in the desired position.
Step 2: Ensure the launch pin is centered on the trace.
Step 3: Ensure the transition block is tight against the board.
Step 4: Tighten the 1-72 mounting screws until the connector is secure.
2. Definitions
Coplanar ground plane spacing = trace width + gap + gap. This is the distance from the inside edge of one top ground plane to the inside edge of the other top ground plane.
Microstrip-to-coplanar transition = When using microstrip on a multilayer board or on a board where the microwave ground is not accessible, then a microstrip-to-coplanar transition should be used.
Transition Block = The portion of the End Launch connector assembly where the high frequency signal transition from the coax connector onto the printed circuit board.
Ground stitching = These are vias connecting the top ground planes with the substrate ground. The purpose of the vias is to ensure both coplanar ground planes stay at the same potential. The best placement of these is near the trace at a distance of ¼ wavelength of the highest frequency.
