ELECTRICAL CHARACTERISTICS

Table 2: Absolute Minimum and Maximum Ratings Table 3: Operating Ranges Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Notes: (1) Pins 3, 5, 8, 10, 19, 20, 25, 26 should be AC-coupled. No external DC bias should be applied. (2) Pins 7 and 22 should be grounded or pulled to ground through a resistor. No external DC bias should be applied. The device may be operated safely over these conditions; however, parametric performance is guaranteed only over the conditions defined in the electrical specifications.

The data is entered in order with the most significant bit (MSB) first and the least significant bit (LSB) last. The enable line must be low for the duration of the data entry, then set high to latch the shift register. The rising edge of the clock pulse shifts each data value into the register. Software is Available from ANADIGICS Application Engineering to set the data bits through the serial cable on the ARA2004 evaluation board.

204313A • Skyworks Proprietary and Confidential Information • Products and Product Information are Subject to Change Without Notice • September 26, 2016 Output Transformer Matching the output of the ARA2004 to a 75 Ohm load is accomplished using a 2:1 turns ratio transformer. In addition to providing an impedance transformation, this transformer provides the bias to the output amplifier stage via the center tap. The transformer also cancels even mode distortion products and common mode signals, such as the voltage transients that occur while enabling and disabling the amplifiers. As a result, care must be taken when selecting the transformer to be used at the output. It must be capable of handling the RF and DC power requirements without saturating the core, and it must have adequate isolation and good phase and amplitude balance. It also must operate over the desired frequency and temperature range for the intended application. ESD Sensitivity Electrostatic discharges can cause permanent damage to this device. Electrostatic charges accumulate on test equipment and the human body, and can discharge without detection. Although the ARA2004 has some built-in ESD protection, proper precautions and handling are strongly recommended. Refer to the ANADIGICS application note on ESD precautions.
