Figure 1. Typical Attenuator Die and Circuit
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.
