AV133-315

HIP3™ Variable Attenuator for UMTS Base Stations AV133-315 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 UMTS Base Stations Description The AV133-315 is a voltage controlled variable attenuator from Alpha’s series of HIP3™ components. It is specifically designed and specified for use as a wide dynamic range low distortion attenuator for UMTS base station applications centered at 2140 MHz. The AV133315 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 AV133-315 is packaged in a small outline LGA (Land Grid Array) surface mount package with the internal elements affixed to an organic BT substrate.
