Important Factors You Need to Know About End Launch Connector

Posted by Boodle Mart on

End Launch Connectors are used to connect a coaxial testcable to a test board. The connector is attached to a PCB board's end or edge then a microwave radiation is sent from a coaxial cable to a circuit on a PCB board using this connector. When compared to vertical-mount or right-angle mount connectors, Gwaveend launch connectors are frequently favored over ordinary connectors because their design lowers reflections. These connections are often utilized for high-frequency or high-performance applications.

  1. How is the end launch connector used?

In this case, microwave energy is transitioned from coaxial to planar transmission-line configurations using end launch connectors. So, Gwave end launch connectors connect test-line coaxial cables to grounded coplanar waveguide (GCPWG) and micro strip circuits on test boards, chip demo sets, and related process boards. To hunt for harmonics, chip and package testing frequently runs to a minimum of three times the operational frequencies, which drives demand for higher-frequency models.

  1. Why is performance important?

Since these connectors are generally used for test ports, performance is critical. Connector design, mounting, board launch layout, as well as PCB material and thickness, are all important factors in application success. Note that connectors should be considered alongside PCB material options in simulation software. So higher-frequency Gwaveend launch connections, typically 8GHz and beyond, do not require soldering since the pin or probe-tip is compressed onto the circuit pad when the connectors are screwed down to the board.

  1. Why is it important to consider the thickness of circuit materials

Furthermore, the transition from coaxial cable assemblies to the PCB is crucial to the circuit's performance, and the thickness of the PCB influences how it is produced. Waveguide and coaxial connectors, like PCB thicknesses, come in a variety of forms and sizes, and matching the connector to the substrate thickness is critical for overall performance. When using non-microwave board materials for signal circuits in multilayer stack-ups with microwave top layers, extra issues arise, requiring partial back-drilling under the connector center pin termination to preserve 50-ohm conditions.

In sum, Gwave end launch connectorsare designed for essential applications that require the highest level of performance. Therefore, users should consult for launch data and validate that the connector, as well as specific launch and board configurations, are tested. Of course, they will improve demo boards and optimize test output if utilized correctly.
