The module connector types vary depending on the operating band and
impedance of the purchased unit:
• The IF Input/Output and LP (Loop) In/Out connectors are typically female
BNC connectors.
• The RF Input/Output and LP (Loop) In/Out connectors may be female
Type ‘N’ or female Type ‘SMA’ connectors, depending on the application.
