Pico Xinger

10dB Directional Coupler

Description

The 1P610 Pico Xinger is a low profile, miniature 10dB directional coupler

in an easy to use surface mount package designed for MMDS and WLAN

applications. The 1P610 is for power and frequency detection as well as

power injection. The 1P610 is an ideal solution for the ever-increasing

demands of the wireless industry for smaller printed circuit boards and high

performance. 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.

Produced with 6 of 6 RoHS compliant tin immersion. Available in both 5 of

6 tin lead (1P610) and 6 of 6 RoHS compliant tin immersion (1P610S).

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 (CONTI NUED)

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 25 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 that negatively affect results.

PIN CONFIGURATION

The 1P610’s have an orientation marker to denote

either pin 1 or pin 2. When the input port is

identified, the output, coupled and isolated ports are

known automatically. For example, if the input port

for a device was selected to be Pin 1, Pin 2

automatically becomes the output port, Pin 4

becomes the coupled port, and Pin 3 is the isolated

port. Similarly, if Pin 2 was to be selected as the

input port, the adjacent port on the long side (Pin 1)

is the output port, the adjacent port on the short side

(Pin 3) is the coupled port, and the opposite port (Pin

4) is the isolated port. Either port on the same side

as the orientation marker can be selected as the

input port, as shown in the table, which shows both

pin configurations. The use of pin 1 or pin 2 as the

input port ensures phase consistency as well as

maximum power handling.

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% solder connection underneath the

part. If either of these two conditions is not satisfied,

insertion loss, coupling, VSWR and directivity may not

meet published specificati ons.
