AV102-12

HIP3™ Variable Attenuator 1.70–2.00 GHz AV102-12 Features I +50 dBm IP3 Typical I Low Loss 1 dB Typical I Attenuation 30 dB Typical I Good VSWR <1.5:1 Typical I Small SOIC-8 Package Description The AV102-12 is a current controlled variable attenuator from Alpha’s series of HIP3™ components. It is designed to meet the wide dynamic range required in spread spectrum wireless base station applications. A monolithic quadrature hybrid is teamed with a silicon PIN diode pair in a plastic surface mount package reducing size and assuring consistency from part to part.
