Image of Analog Devices' ADL8104 Low Noise Amplifier ADI's 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.

The ADL8104 provides typical gain of 15 dB at 0.6 GHz to 6 GHz and 3.5 dB typical noise figure at 0.4 GHz to 6 GHz. It provides 20 dBm typical output power for 1 dB compression (OP1dB) at 0.6 GHz to 6 GHz and 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 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.
