Description

To meet the need for higher performance,

impedance matched cable interconnections,

Amphenol offers a full line of 75 ohm BNC

connectors. These connectors can be used in a

variety of applications where true 75 ohm

performance is needed to insure lower signal

distortion.

Features/Benefits

Designed for the most popular 75 ohm cables used

in broadcast and CATV applications as well as for

plenum cables and others — these connectors fea-

ture crimp-crimp cable affixment for quick and reli-

able installation.

Two distinct types of 75Ω BNCs are available. Both

types mate with each other and with 50Ω BNCs.

• Type 1 is designated 75Ω BNC-T1 and

provides constant 75Ω perfomance with low

VSWR DC to 4 GHz.

• Type 2 is designated 75Ω BNC-T2 and is usable

with low reflection DC to 1 GHz. For applications

above 1 GHz, Type 1 is recommended.

Applications

• Broadcast

• Satellite TV Earth Stations

• Telecommunications

• LAN

• Test and Measurement

• Security Transmission Systems

• Telecom

• Computer Networks

• HDTV
