2AM0405S

Variable Gain Amplifier Product Features • Multi-chip hybrid module • MESFET&HBT chip on board • 2 stage Gain Block amplifier Which includes a digital attenuator • 6-bit RF digital step attenuator covering a 31.5dB attenuation range in 0.5dB steps • Module system simplification • No External Matching Circuit Needed • Cutom Design Available • Alumina Substrate • Pb Free / RoHS Compliant 2AM Series Application • Repeater • Base Station • RF Sub-Systems • IMT, WCDMA, UMTS, Wimax, Wibro Package : CP-5CS Description Variable Gain Amplifier 2AM Series can be used in any applications that need Gain Control according to Input Signal Level. Also, 2AM Series can be applied to various frequency system combined with GaAs MESFET or InGaP HBT MMIC. 2AM series are a hybrid module which has 2-stage Amplifier chip and Attenuator chip mounted on a Ceramic board. Attenuator is 0.5dB step 6-bit digital attenuator which has 31.5dB of total attenuation. Original version use GaAs MESFET amplifiers but RFHIC can customize the amplifier IC used in the hybrid to be either HBT, E-pHEMT or any other technology depending on specification requirements.
