Preliminary HIP3™ Variable Attenuator for AMPS and GSM Base Stations AV131-315 Features ■ 23 dB Attenuation Range ■ 1.5 dB Insertion Loss, 1.5 SWR ■ 0–12 V Control Voltage ■ 43 dBm IP3 ■ Small Footprint LGA Package ■ Designed for AMPS and GSM Base Stations Description The AV131-315 is a voltage controlled variable attenuator from Skyworks’ series of HIP3™ components. It is specifically designed and specified for use as a wide dynamic range low distortion attenuator for AMPS and GSM base station applications centered at 881.5 MHz and 942.5 MHz. The AV131-315 employs a monolithic quadrature hybrid and a pair of silicon PIN diodes to achieve the specified low distortion performance. It operates from 0–12 V at 1.6 mA typical control current at maximum attenuation. The AV131-315 is packaged in a small outline LGA (Land Grid Array) surface mount package with the internal elements affixed to an organic BT substrate.
