Description

The ATN3590 family of fixed resistive attenuators are integrated

circuits comprising thin film resistors and through-die vias that

provide excellent attenuation flatness from low frequency to

40 GHz or higher. These attenuators are available from 0 to 30 dB

(see Table 2).

The ATN3590 attenuator family is optimized for surface mounting

on co-planar waveguide or microstrip printed circuit boards. Bond

wires or ribbons are used to connect the input and output ports of

the attenuators to the external circuit transmission lines.

Connection to ground is accomplished by through-die vias to the

die backside metallization.

The dice are attached using eutectic solder or conductive epoxy

and can operate over a temperature range of –65 C to 150 C.

The absolute maximum ratings for the ATN3590 attenuators are

provided in Table 1 and the electrical specifications are shown in

Table 2. Typical performance characteristics are illustrated in

Figures 2 through 8.
