RF Adaptor Kit

Product Overview

This series adaptor can implement the interconnection and conversion between the
different types interfaces. It features good frequency performance and impedance
matching as well as low insertion loss. It can be used in common test and calibration
measurement.

N Type Connector

N type connector is a durable medium-size connector mainly used
in medium-size micro coaxial cables. Figure (a) and figure (b) on
the right side show the AD-NF-NF-18501 (dual-N female) model
and AD-NM-NM-18501 (dual-N male) model N type connectors
respectively.

N-SMA Connector

N-SMA connector is used to connect the N connector and SMA
connector. It is an anti-water and anti-shock high frequency
coaxial connector. This series of connectors are mainly used in
mobile communication instrument connection and N-to-SMA
connection. The figure on the right side shows the
AD-NM-SMAF-12501 model N (male)-SMA (female) connector.

N-BNC Connector

BNC T Type Connector

BNC T type connector is a widly used coaxial adapto
small size, light weight and fast assemble/disassemble. The figure
on the right side shows the AD-BNCF-BNCM-BNCF-04501 model
BNC T type connector.

50 Ω Impendance Adaptor

his type of impedance adaptor can be used in the RF source and
other equipments, e.g., convert the input resistance of the external
modulation input interface to 50Ω. It also can be used to connect
the oscilloscope test prod and electric meter. It can match the
impedance of the oscilloscope test prod with that of the electric

meter to obtain correct measurement value.
