APPLICATIONS

►Test instrumentation ►Military communications ►Radar GENERAL DESCRIPTION The ADL8107 is a gallium arsenide (GaAs), monolithic micro- wave IC (MMIC), pseudomorphic high electron mobility transistor (pHEMT), low noise, wideband, high linearity amplifier that operates from 6 GHz to 18 GHz. The ADL8107 provides a typical gain of 24 dB at 7 GHz to 16 GHz, a 1.3 dB typical noise figure at 7 GHz to 16 GHz, a 18.5 dBm typical output power for 1 dB compression (OP1dB) at

7 GHz to 16 GHz, and a typical output third-order intercept (OIP3)

of 29 dBm at 7 GHz to 16 GHz, requiring only 90 mA from a 5 V drain supply voltage. This low noise amplifier has a high output sec- ond-order intercept (OIP2) of 30.5 dBm typical at 7 GHz to 16 GHz, making the ADL8107 suitable for military and test instrumentation applications. The ADL8107 also features inputs and outputs that are internally matched to 50 Ω. The RFIN and RFOUT pins are internally ac-cou- pled, and the bias inductor is also integrated, making the ADL8107 ideal for surface-mounted technology (SMT)-based, high density applications. The ADL8107 is housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP. FUNCTIONAL BLOCK DIAGRAM Figure 1.
