Model XDL09-9-224S
Rev. D
Delay Line
Description
The XDL09-9-224S is a surface mount delay line that uses a slow wave coupling structure that maximizes the amount
of delay per unit area over other distributed delay structures. The XDL09-9-224S can be used in amplifier linearization
applications from 855 – 894 MHz. The XDL09-9-224S is ideal for the delay element required in the main loop of feed
forward amplifiers. The Xinger® delay lines are a low cost, high quality alternative to the traditional coaxial and filter
solutions presently available. Parts have been subjected to rigorous qualification testing and units are 100% tested.
Produced with 6 of 6 RoHS compliant tin immersion

AVERAGE DELAY
The average delay is defined as the group delay of the input signal through the delay line. The lot-to-lot variation is
reflected in the plus/minus tolerance given in specifications.
Refer to Anaren Application Note AAN-232 for further information on Xinger delay lines.
Mounting Guidelines:
To insure proper electrical and thermal performance
there must be a ground plane with 100%
solder connection underneath the part

In order for Xinger surface mount delay lines to work
optimally, there must be 50Ω transmission lines leading to
and from all of the RF ports. Also, there must be a very
good ground plane under the part with a number of plated
thru holes to ensure proper electrical performance. If any
of these conditions are not satisfied, insertion loss,
average delay and VSWR may not meet published
specifications.
When a surface mount delay line is mounted to a printed
circuit board (PCB), the primary concerns are; insuring
the RF pads of the device are in contact with the circuit
trace of the PCB and the ground plane of neither the
component nor the PCB are in contact with the RF signal.
An example of how the PCB footprint could look is shown
below. In particular designs, the 50Ω lines need to be
adjusted to the unique dielectric coefficients and
thicknesses as well as varying pick and place equipment
tolerances.
