Agilent X/P/K281C Adapters Operating and Service Manual

Introduction
Product Overview
The X281C, P281C, and K281C adapters provide a
convenient means of coupling between waveguide and
coaxial systems. Power can be transmitted in either
direction, and each adapter covers the full frequency range
of its waveguide size. A step- like internal structure
transforms the waveguide impedance to the 50
Ω
impedance
of the coaxial line.
Options
Option 006
Option 006 adds two alignment holes to the waveguide
flange. The dimensions of the Option 006 alignment holes
are provided in the following table.
