GaAs High Linearity Noise Amplifier
Avago Technologies AMMC-6232 easy-to-use broadband, high gain, high linearity Noise Amplifier that operates from 32GHz. wide band unconditionally stable performance makes this MMIC ideal primary sub-sequential noise block transmitter driver. MMIC gain stages requires 135mA power supply optimal performance. gate bias voltages combined ease separated more control flexibility. DCblock capacitors integrated input output stages. Since this MMIC covers several bands, reduce part inventory increase volume purchase options MMIC fabricated using PHEMT technology provide exceptional noise, gain power performance. backside chip both ground which helps simplify assembly process reduce assembly related performance variations cost.
