ADL5323

Data Sheet FEATURES Internally matched to 50 Ω input and output Internally biased Operating frequency: 1700 MHz to 2400 MHz Gain: 20 dB OIP3: 43 dBm P1 dB: 28 dBm Noise figure: 5 dB 3 mm × 3 mm LFCSP Power supply: 5 V APPLICATIONS CDMA2000, WCDMA, and GSM base station transceivers and high power amplifiers 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. 1700 MHz to 2400 MHz GaAs Matched RF PA Predriver ADL5323 FUNCTIONAL BLOCK DIAGRAM INPUT MATCH 06058-001 VCC 5 GND 6 GND 7 RFIN 8 BIAS CONTROL OUTPUT MATCH ADL5323 Figure 1. 4 RFOUT 3 GND 2 VCC 1 VCC (dBm) 06058-014 –15 –20 –30 –40 –50 –60 –70 –80 –90 –100 –110 –115 CENTER 2.14GHz RBW = 30kHz VBW = 300kHz SWT = 2s RF ATT = 10dB CH PWR = 0dBm ACP UP = –74.2dBc ACP LOW = –73.9dBc 1.46848MHz/ SPAN 14.6848MHz Figure 2.
