Insertion Loss and Power Derating Curves
Insertion Loss Derating:
The insertion loss, at a given frequency, of a group of
couplers is measured at 25°C and then averaged. The
measurements are performed under small signal
conditions (i.e. using a Vector Network Analyzer). The
process is repeated at -55°C and 85°
C. Based on
copper as well as dielectric losses, the insertion loss is
computed from -55°C to 300°C.
Power Derating:
The power handling and corresponding power derating
plots are a function of the thermal resistance, mounting
surface temperature (base plate temperature),
max
imum continuous operating temperature of the
coupler, and the thermal insertion loss. The thermal
insertion loss is defined in the Power Handling section of
the data sheet.
As the mounting interface temperature approaches the
maximum continuous operating temperature, the power
handling decreases to zero.
If mounting temperature is greater than 85°C, Xinger
coupler will perform reliably as long as the input power
Is derated to the curve above.

Mounting
In order for Xinger surface mount couplers 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 underneath the part to ensure
proper electrical performance. If either of these two
conditions is not satisfied, insertion loss, coupling, VSWR
and isolation may not meet published specifications.
Overall ground is improved if a dense population of
plated through holes connect the top and bottom ground
layers of the PCB. This minimizes ground inductance
and improves ground continuity. All of the Xinger hybrid
and directional couplers are constructed from ceramic
filled PTFE composites which possess excellent electrical
and mechanical stability.
When a surface mount hybrid coupler is mounted to a
printed circuit board, the primary concerns are; ensuring
the RF pads of the device are in contact with the circuit
trace of the PCB and insuring the ground plane of neither
the component nor the PCB is in contact with the RF
signal.

Coupler Mounting Process
The process for assem
bling this component is a
conventional surface mount process as shown in Figure
1. This process is conducive to both low and high volume
usage.
Figure 1: Surface Mounting Process Steps
Storage of Components: The Xinger II pr
oducts are
available in an immersion tin finish. Commonly used
storage procedures used to control oxidation should be
followed for these surface mount components. The
storage temperatures should be held between 15OC and
60OC.
Substrate: Depending upon th
e particular component,
the circuit material has a coefficient of thermal expansion
(CTE) similar to commonly used board substrates such
as RF35, RO4003, FR4, polyimide and G-10 materials.
The similarity in CTE minimizes solder joint stresses due
to simila
r expansion rates between component and
board. Mounting to “hard” substrates (alumina etc.) is
possible depending upon operational temperature
requirements. The solder surfaces of the coupler are all
copper plated with an immersion tin finish.
Solder Paste: All conventional solder paste formulations
will work well with Anaren’s Xinger II surface mount
components. Solder paste can be applied with stencils or
syringe dispensers. An example of a stenciled solder
paste deposit is shown in Figure 2. As shown in the
figure solder paste is applied to the four RF pads and the
entire ground plane underneath the body of the part.

Figure 2: Solder Paste Application
Coupler Positioning: The surface mount coupler can
be placed manually or with automatic pick and place
mechanisms. Couplers should be placed (see Figure 3
and 4) onto wet paste with common surface mount
techniques and parameters. Pick and place systems
must supply adequate vacuum to hold a 0.50-0.55
gram coupler.
Figure 3: Component Placement
Figure 4: Mounting Features Example
Reflow: The surface mount coupler is conducive to most of
today’s conventional reflow methods. A low and high
temperature thermal reflow profile are shown in Figures 5
and 6, respectively. Manual soldering of these components
can be done with conventional surface mount non-contact
hot air soldering tools. Board pre-
heating is highly
recommended for these selective hot air soldering
methods. Manual soldering with conventional irons should
be avoided.
