AV111-12

HIP3™ Variable Attenuator 0.80–1.00 GHz AV111-12 Features I +40 dBm IP3 Typical I Low Loss 1 dB Typical I Attenuation 30 dB Typical I Good VSWR <1.5:1 Typical I Low Phase Shift SOI C-8 SOI C-8 Description The AV111-12 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.
