The element14 ESSENTIALS of RF and End Launch Applications discusses RF communication fundamentals and some applications of end launch connectors. To extend the knowledge covered in the main module, this supplementary guide discusses the types of related components that can be used for products or prototyping.
The SMPM bullet adapter provides the same coveted blind mate functionality as the larger SMP size connectors, mitigating radial and axial misalignment with negligible change to VSWR and other signal losses. The SMPM-series is good for test equipment and racked electronics, where footprint space is a premium and mating boards together is difficult.
The SMPM family includes PC mount and End Launch styles, straight/right-angled, .047 cabled connectors, and sealable flange mounts. All male connectors are offered as a full detent or smooth bore designs for your preference of separation forces.
The 1.85mm Screw On Board Edge, End Launch Jack is designed for use in a variety of applications while delivering signal integrity in demanding environments. Easy to assemble and disassemble to a PCB, they can be connected with solder or solderless, and adjustable to varying board thicknesses.
The SMA Self-Fixture End Launch Jack Assembly with round contact attaches directly to a coplanar waveguide circuit board and operates up to 18 GHz with good return loss values. This enhanced end launch connector properly aligns and holds the center contact of a coaxial connector to the circuit board plane without the need for fixtures.
145-0701-802 - End Launch Jack RF / Coaxial Connector, SMK Coaxial, Straight Jack, Screw, 50 ohm, Beryllium Copper
The Johnson 2.92mm Connector provides an end launch solution for demanding applications requiring high frequency transmission. Although similar to the SMA interface, a smaller internal body diameter (2.92mm) and air dielectric provide a higher cutoff frequency.
A straight SMA Coaxial Jack with gold-plated beryllium copper contact. This is used to transition microwave energy from coaxial to planar transmission line structures. This patent-pending connector provides a unique solution for microwave engineers who fabricate circuit designs on fragile high-frequency board substrates. The in-line connector design minimizes reflections as compared to a right-angle (perpendicular) pc mount transition.
An RF/Coaxial Connector, SMA straight jack receptacle with gold plated brass body; gold-plated contact, printed circuit board style, solder termination type and Surface Mount.
This end launch SMA RF Coaxial Connector is attached to the circuit board by inserting the board edge between the legs and soldering the legs and center conductor to pads on the board. For optimum high-frequency performance, the connector to circuit board transition must be adjusted for low VSWR. To compensate for the transition from coax to microstrip, trace widths "A" and "B" must be adjusted based on circuit board thickness. When properly adjusted, this technique yields a low VSWR over a wide bandwidth.
An RF/Coaxial Connector, SMA PC mount jack receptacle with gold plated brass body; gold-plated contact, printed circuit board style, solders termination type, and end launch mount. This high-frequency end launch connector is designed to attach directly to a high-frequency coplanar waveguide (CPW) circuit board transmission line, although other lines such as microstrip can be used with good results. These connectors can be used on high-frequency PC board substrate layers as thin as 10 MIL pin.
