The ADL5322 is a high linearity GaAs driver amplifier that is internally matched to 50 Ω for operation in the 700 MHz to 1000 MHz frequency range. The amplifier, which has a gain of 20 dB, is specially designed for use in the output stage of a cellular base station radio or as an input preamplifier in a multicarrier base station.
The ADL5322 is a high‑linearity GaAs driver amplifier internally matched to 50 Ω for operation between 700 MHz and 1000 MHz. It is designed for use in the output stage of cellular base‑station radios or as a pre‑amplifier in multicarrier power‑amplifier chains, with applications in CDMA2000, WCDMA, and GSM base‑station transceivers.
Key specifications include 20 dB gain, 5 dB noise figure, 27 dBm P1dB, 45 dBm OIP3, and operation from –40 °C to +85 °C. The device is supplied in a 3 mm × 3 mm 8‑lead LFCSP package and requires a 5 V supply with typical 320 mA current draw.
