6dB Directional Coupler
t
Description
The JP506 is a low profile 6dB directional coupler in an easy to use surface
mount package covering the WCDMA and other 3G applications. The
JP506 is ideal for an inline split/combine amplifiers and for power injection
and can be used in most high power designs. Parts have been subjected to
rigorous qualification testing and units are 100% tested. They are
manufactured using materials with x and y thermal expansion coefficients
compatible with common substrates such as FR4, G-10 and polyamide.

COUPLING
Choice of a coupling value in an application normally
depends on the power level of the main (sampled) line.
For example, if the coupler is being used to monitor main
line power, the coupling value is selected to provide
sufficient power to the monitoring device and yet
minimize system loss. Note that any coupler reduces
power flowing in the main line by the amount coupled off;
a 10dB coupler reduces main line power by 1 dB (10%)
where a 20dB coupler reduces it by only 0.044dB (1%).
Anaren uses mean coupling and frequency sensitivity
with the coupling specification. The mean coupling value
is arrived at by periodically sampling the coupling value
over the specified band and averaging the readings.
Frequency sensitivity is the peak to peak variation in
coupling over the specified band.
VSWR & DIRECTIVITY
In directional couplers, directivity is specified in lieu of
isolation. Directivity is a measure of how well the coupled
power is isolated from reflections at the main line output
port. For example, open or short circuiting the output port
of a coupler with 20dB directivity would only affect the
coupled output power by 1% and only 0.1% for 30dB
directivity. High directivity is especially important if the
coupler is being used to measure the VSWR of a device
at its output port.
In this application, accurate
measurements of forward and reverse power are
required.
In theory, VSWR and directivity characteristics of a
coupler are perfect; the input and output ports are
perfectly matched and no power is coupled to the isolated
port. In practice, factors associated with the design and
manufacturing processes limit VSWR and directivity. The

VSWR & DIRECTIVITY (CONTINUED)
internal meandering of the coupled lines and limitations
of building perfect 50Ω transitions at the input and
output ports of the device are the most significant
factors against perfect VSWR and directivity. Typically,
VSWR and directivity of 1.15:1 and 20 dB respectively
are achieved in practice.
INSERTION LOSS
Coupler insertion loss is defined as the log of the input
power divided by the sum of the power at the two
output ports. In practice, typical loss is approximately
0.20 dB. Specification limits are somewhat higher due
to imperfect test conditions; surface mount couplers
must be tested in test fixtures which negatively affect
results.
PIN CONFIGURATION
MOUNTING
For Xinger surface mount couplers to operate
optimally, there must be 50Ω transmission lines
leading to and from all of the RF ports. To ensure
proper electrical and thermal performance, there
must be a ground plane with 100% colder
connection underneath the part. If either of these
two conditions is not satisfied, insertion loss,
coupling, VSWR and directivity may not meet
published specifications.
SUGGESTED FOOTPRINT
To ensure proper electrical and thermal performance
there must be a ground plane with 100%
solder connection underneath the part
