GENERAL DESCRIPTION
The ADL5521 is a high performance GaAs pHEMT low-noise amplifier. It provides high gain and low noise figure for single downconversion IF sampling receiver architectures as well as direct down conversion receivers. The ADL5521 also has low power consumption at 3 V.
The ADL5521 allows optimal noise matching without sacrificing significant gain matching. S11 of better then 6 dB can typically be achieved when matching for optimal noise.
