GENERAL DESCRIPTION The ADL5323 is a high linearity GaAs driver amplifier that is internally matched to 50 Ω for operation in the 1700 MHz to 2400 MHz frequency range. The amplifier, which has a gain of 20 dB, has been specially designed for use in the output stage of a cellular base station radio or as an input preamplifier in a multicarrier base station power amplifier. Matching and biasing are all on-chip. The ADL5323 is available in a Pb-free, 3 mm × 3 mm, 8-lead LFCSP with an operating temperature of −40°C to +85°C. –15 –115 CENTER 2.14GHz SPAN 14.6848MHz 1.46848MHz/ –50 –60 –70 –80 –90 –100 –30 –40 –20 –110 RBW = 30kHz VBW = 300kHz SWT = 2s RF ATT = 10dB CH PWR = 0dBm ACP UP = –74.2dBc ACP LOW = –73.9dBc Figure 2.
