High Frequency SMA End Launch Connectors
Mounting Instructions
Mounting Footprint Info
1. All of the drilled holes are plated through the entire circuit board stackup.
2. All hole patterns are symmetrical about center of the trace.
3. The recommended mounting footprints are shown for the top (signal) side of the board only. Use ground planes on additional layers where
appropriate.
4. For optimum high frequency circuit board performance, use the following fabrication guidelines:
A. Maintain a solid ground plane below the high frequency substrate layer.
B. Control the pullback of the trace and grounds from the board edge.
C. Continue the grounded coplanar waveguide line beyond the ground pad area.
D. Place 16 mil diameter ground vias on both sides of the coplanar waveguide line, spaced at 50 mil intervals along the entire length of
the line.
E. Immersion gold plate (ENIG) all high frequency conductors per IPC-4552.
F. Do not coat the coplanar waveguide signal trace or open ground gaps with soldermask.

* These calculated dimensions assume a quasi-static mode of propagation, but dispersion does exist for coplanar waveguide. The characteris-
tic impedance and effective dielectric constant may increase slightly for X-band and higher frequencies, unless very small ground to ground
gap spacing is used.
It is assumed the conductors have rectangular cross-sections. The etching process used in circuit board fabrication actually produces trape-
zoidal shapes. Therefore, the GCPW impedance may increase somewhere between that of a perfect rectangular conductor and a theoretical
zero thickness conductor.
