The attenuator DC blocking capacitors (C ) and biasing resistor must be supplied externally for positive BL voltage operation. requires external DC blocking capacitors, positive supply voltage C = 47 pF for operation >500 MHz. BL (V ) and four individual positive control voltages (V V ). The S 1 4 AA264-87 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include base station, wireless data and wire- less local loop gain control circuits.
