Typical Attenuator Die and Circuit 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.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry- standard ESD handling precautions should be used at all times. Table 2.

Input Return Loss vs Frequency Figure 8. Small Signal Gain vs Frequency Technical Description R3 The ATN3590 family of fixed attenuators comprises devices with R1 nominal attenuation values of 0 to 10 dB (in 1 dB steps), and 12, 15, 20, and 30 dB. These attenuators contain through-wafer vias R4 that connect the topside ground to the backside metallization of R2 each die. The devices with nominal attenuation values of 1 dB or greater are fabricated using thin film resistors deposited on GaAs Figure 9. Circuit Topology (1 to 5 dB Attenuators) substrates. The circuit topology is a simple tee structure that consists of two series resistors and a shunt resistance, which in this case is realized as a pair of shunt resistors connected to the R1 R4 node between the two series resistors (refer to Figures 9 and 10). The resistances of each of these resistors are selected to simultaneously produce the nominal attenuation with very good input and output return losses. R2 || R3 The attenuators with nominal attenuation values ≥6 dB contain a pair of cascaded tee sections (see Figure 11). The 0 dB attenuator, ATN3590-00, is a 50 Ω microstrip transmission line Figure 10. Simplified Circuit Topology (1 to 5 dB Attenuators) with identical foot print and bond pads to those of the other products in this family. R3 R5 Die Attachment and Signal Path Connection R1 Any of the ATN3590 family of attenuators should be mounted on the ground plane of a transmission medium. The die should be R4 R7 attached with conductive epoxy or a eutectic solder such as gold/tin (AuSn). R2 R6 For good high frequency performance, it is essential that there is no ground plane directly beneath the series signal path of the ATN3590. The backside metallization on the die is split into two Figure 11. Circuit Topology for Attenuators with Nominal regions along the sides of the die to accommodate this Attenuation ≥6 dB requirement.
