LAYOUT

Solder the exposed pad on the underside of the ADMV7320 to a

low thermal and electrical impedance ground plane. This pad is

typically soldered to an exposed opening in the solder mask.

Connect these ground vias to all other ground layers to maximize

heat dissipation from the device package.

Figure 84 illustrates the recommended mechanical layout on

the interface plate used to interface to the WR-12 waveguide

opening of the ADMV7320. The recommended PCB land

pattern footprint is shown in Figure 85.

NOTES:

1. REMOVE BURRS AND BREAK SHARP EDGES.

2. ALL INTERNAL RADII ARE 0.090 UNLESS OTHERWISE NOTED.

3. SURFACE FINISH 32 RMS UNLESS OTHERWISE SPECIFIED.

4. DIMENSIONS APPLY AFTER PLATING.

5. MATERIAL: ALUMINUM 6061-T6 PER QQ-A-250/11.

6. FINISH: NONE.

7. INSTALL DOWEL PINS.

8. USE ELECTRONIC DATA FOR ALL GEOMETRY THAT IS NOT DIMENSIONED.
