10-27GHz Bidirectionnal Detector
GaAs Monolithic Microwave IC in SMD leadless package
Description
UMS
E1260
YYWW
The CHE1260-QAG is a bidirectionnal
detector
that
integrates
a
passive
bidirectionnal coupler, two matched detector
diodes and two reference diodes.
It allows the measurement of transmitted
and reflected power. It is designed for a wide
range of applications where an accurate
transmitted power control is required,
typically
commercial
communication
systems.
Vref_R DC_R
Vdet_R
RF_in

CHE1260-QAG
Typical Measured Performance: Notes
The CHE1260-QAG is a bidirectionnal detector using a symmetrical bidirectionnal coupler.
Therefore the incident power detection versus incident power is identical to the reflective
power detection versus reflected power.
The reflective power detection versus incident power depends on both the coupler directivity
and the reflective environment of the package.
The following typical measured performances are obtained for a packaged detector,
assembled on a connectorized board.

Definition of the Sij reference planes
The reference planes used for Sij
measurements given above are
symmetrical from the symmetrical axis
of the package (see drawing beside).
The input and output reference planes
are located at 2.65mm offset (input
wise and output wise respectively)
from this axis. Then, the given Sij
parameters
incorporate
the
recommended land pattern of the
evaluation motherboard .
Recommended package footprint
Refer to the application note AN0017 available at http://www.ums-gaas.com for
package foot print recommendations and exact package dimensions.
SMD mounting procedure
The SMD leadless package has been designed for high volume surface mount PCB
assembly process. The dimensions and footprint required for the PCB (motherboard)
are given in the drawings above.
For the mounting process standard techniques involving solder paste and a suitable
reflow process can be used. For further details, see application note AN0017.
Recommended environmental management
Refer to the application note AN0019 available at http://www.ums-gaas.com for
environmental data on UMS package products.
Recommended ESD management
Refer to the application note AN0020 available at http://www.ums-gaas.com for ESD
sensitivity and handling recommendations for the UMS package products.

Recommended external resistors assembly
100kΩ resistors in parallel with Vdet_I, Vref_I, Vdet_R and Vref_R pads are recommended
to provide the best behaviour in the whole operating temperature range.
Best accuracy is obtained when:
Vdetect_ I= Vref_R- Vdet_I
Vdetect_R= Vref_I- Vdet_R
As the voltage detection is the difference between Vref_X and Vdet_X (X= I or R), the
external resistor value should be identical on these ports.
For information, a variation of 2% leads around 1mV variation of detected voltage.
ESD protections are implemented on Vdet_I, Vref_I, Vdet_R and Vref_R accesses.
The DC connections (DC_R & DC_I) do not include any decoupling capacitor in package,
therefore it is mandatory to provide a good external DC decoupling on the PC board, as
close as possible to the package.
