Chapter 3 — Power Sensor Care 3-3 RF Connector Precautions
Clean the Connectors
The precise geometry that makes the RF component’s high
performance possible can easily be disturbed by dirt and other
contamination adhering to the connector interfaces. When not in
use, keep the connectors covered. Connector s must be cleaned
using a lint-free cotton swab that has been dampened with
isopropyl alcohol (IPA). Refer to
Section 3-6 “Connector Cleaning”
on page 3-10 for specific details.
3-3 RF Connector Precautions
Handle With Care
RF connectors are designed to withstand years of normal bench
handling. However, do not drop or otherwise treat them roughly.
They are laboratory-quality devices, and like other such devices,
they require careful handling.
Keep Connectors Clean
Avoid touching connector mating planes with bare hands.
Natural skin oils and microscopic dirt particles are very hard to
remove.
When using cotton swabs to clean connectors, make sure that you
don’t damage the center conductor. Refer to
Section 3-6 .
Check the Pin Depth
Always check the pin depth of a new connector before use to
determine if it is out of spec. One bad connector can damage
many. The connector can be damaged by turning in the wrong
direction. Turning right tightens and turning left loosens.
Teflon Tuning Washers
The center conductor on most RF components contains a small
teflon tuning washer located near the point of mating (interface).
This washer compensates for minor impedance discontinuities at
the interface. The washer’s location is critical to the RF
component’s performance. Do not disturb it.
