This device is ideally suited for use where high accuracy, very low power consumption and low intermodulation products are required. Typical applications include Cellular Basestation RX/TX Line-up, Femtocells, and other gain / level control circuits. This attenuator is controlled with either a SPI compatible serial interface or a 6 bit parallel word. Functional Schematic 3,4 3. Blocking capacitors are required on all RF ports. 4. For optimum RF performance all N/C’s should be terminated to GND.
