Delay Line
DESCRIPTION __________
The XDL20-11-180S 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 XDL20-11-180S can be used in
amplifier linearization applications from 869–894 MHz. The XDL20-11-180S
is ideal for use in the main loop of feed forward and in pre-distortion
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:
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.
To ensure proper electrical and thermal performance
there must be a ground plane with 100% solder
connection underneath the part

XDL20-11-180S Mounting Footprint
Multiple Plated
Thru Holes
to Ground
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.
