Amphenol® High Frequency Contacts
Provide High Speed Transmission
Operate in High Frequency Conditions
When you need superior electrical performance plus shielding to eliminate
interference from outside electrical sources in a connector, Amphenol has the
most reliable contact solutions.
Amphenol offers a very wide range of contacts that provide high speed transmission and operate
in high frequency conditions. You can be assured of interconnection compatibility when you come
to Amphenol for your contact needs as well as your connector needs. Amphenol’s expertise in
interconnection solutions assures that your contacts will mate properly and will perform to the
application specifications of your particular requirements.
MIL-DTL-38999 CONNECTORS - The high performance series most ideal for integrating high
speed and high frequency contacts. MIL-DTL-38999, Series I, II and III are by far the choice of
connector for today’s avionics needs - these subminiature family connectors are ideally suited for
the incorporation of shielded contacts.

The Cable Usage Guide is a key reference to help guide you in selecting the contacts best suited to
your needs. Since most shielded wire applications start with a fixed requirement for cable types, the
guide refers you to the Amphenol connector family utilizing contacts which are compatible with the
cable characteristics.
