5-44GHz Detector

GaAs Monolithic Microwave IC in SMD leadless package

Description

The CHE1270-QAG is a detector that

integrates a matched detector diode (Vdet)

and a reference diode (Vref).

It is designed for a wide range of applications

where an accurate transmitted power control

is required, typically commercial

communication systems.

The circuit is manufactured with a Schottky

diode MMIC process, 1µm gate length, via

holes through the substrate and air bridges.

It is supplied in RoHS compliant SMD

package.

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 land pattern of

the evaluation motherboard recommended in

paragraph "Evaluation mother board".

Recommended external resistors assembly

27kΩ resistors in parallel with Vdet and Vref pads are recommended to provide the best

behaviour in the whole operating temperature range.

As the voltage detection is the difference between Vref and Vdet, the external resistor value

should be identical on these two ports.

For information, a variation of 3% leads around 1mV variation of detected voltage.

Due to ESD protection circuits on RF input, an external capacitance might be requested to

isolate the product from external voltage that could be present on the RF access.

ESD protections are also implemented on Vdet and Vref accesses.

The DC connection (on DC pad) does 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.
