Use, Maintenance, and Care of the Devices
Connections
b. Check the flange matings for any gap. A good connection has no gaps between the
connected waveguide flanges, and the waveguide walls are flush (there is no step or
offset).
c. Inspect the washers for symmetrical compression. This ensures that all four screws
are equally torqued.
How to Connect:
Q-band WR-22
U-band WR-19
V-band WR-15
W-band WR-10
To ensure proper flange mating, each device has two attached alignment pins, and two
alignment holes through which you slide additional pins. You don’t have to use nuts or
washers when connecting Q, U, V, or W-band waveguide. The flanges have tapped screw
holes; captive screws (threaded half-way up the shaft) are provided in these kits.
Follow these recommendation for optimum connection technique:
1. Install four captive screws into the test port.
2. Install the alignment pins.
3. Using the pins as a guide, bring the flanges together and gently engage the first few
threads of each screw.
4. In an X pattern (for equal compression), use the hex ball driver to tighten all four
screws. Do not over-tighten.
5. Visually inspect the connection:
a. Place an electric light or white paper behind the connection.
b. Check the flange mating for any gap. A good connection has no gaps between the
connected waveguide flanges, and the waveguide walls are flush (there is no step or
offset).
