GENERAL DESCRIPTION
The ADL8104 is a gallium arsenide (GaAs), monolithic
microwave integrated circuit (MMIC), pseudomorphic high
electron mobility transistor (pHEMT), low noise, wideband,
high linearity amplifier that operates from 0.4 GHz to 7.5 GHz.
high output second-order intercept (OIP2) of 52 dBm typical at
0.6 GHz to 6 GHz, making the ADL8104 suitable for military
and test instrumentation applications.
The ADL8104 also features inputs and outputs that are
internally matched to 50 Ω. The RFIN and RFOUT pins are
internally ac-coupled and the bias inductor is also integrated,
making the ADL8104 ideal for surface-mounted technology
(SMT)-based, high density applications.
The ADL8104 provides a typical gain of 15 dB at 0.6 GHz to
6 GHz, a 3.5 dB typical noise figure at 0.4 GHz to 6 GHz, a
20 dBm typical output power for 1 dB compression (OP1dB) at
0.6 GHz to 6 GHz, and a typical output third-order intercept
(OIP3) of 32 dBm at 0.6 GHz to 6 GHz, requiring only 150 mA
from a 5 V drain supply voltage. The low noise amplifier has a
The ADL8104 is housed in an RoHS-compliant, 3 mm × 3 mm,
16-lead LFCSP.
