DATA SHEET AA104-73/-73LF: 300 kHz-2.5 GHz One-Bit Digital Attenuator (32 dB) Applications • Sixth-bit value for Skyworks AA260-85 and AA101-80 digital attenuators • IF and RF components for cable, GSM, PCS, EDGE, 3G, and ISM systems Features • One-bit attenuation of 32 dB (300 kHz to 1 GHz), 27 dB (1 GHz to 2 GHz), 24 dB (2 to 2.5 dB) • Combines with Skyworks AA260-85 or AA101-80 digital attenuators for a 63 dB, six-bit solution • Tune with one capacitor and/or resistor to desired operating frequency and attenuation • Small SOT-6 package (MSL1, 260 °C per JEDEC J-STD-020) Figure 1. AA104-73/-73LF Block Diagram Description The AA104-73/-73LF are one-bit GaAs FET digital attenuators in a low-cost SOT-6 package. These devices provide up to 32 db total attenuation requiring two lines of voltage control. The AA104-73/-73LF are particularly suited where high attenuation accuracy, low insertion loss, and low intermodulation products are required. A typical application is as a sixth-bit value for the AA260-85 and AA101-80 digital attenuators. A total attenuation of 63 dB in 1 dB steps can be obtained by combining the two attenuators. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Figure 2.

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. CAUTION: 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. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. Electrical and Mechanical Specifications The absolute maximum ratings of the AA104-73/-73LF are provided in Table 2. Electrical specifications are provided in Tables 3, 4, 5, and 6. The state of the AA104-73/-73LF is determined by the logic provided in Table 4. Typical performance characteristics of the AA104-73/-73LF are illustrated in Figures 3 through 13.
