GENERAL DESCRIPTION

The ADL9005 is a gallium arsenide (GaAs), monolithic microwave

integrated circuit (MMIC), pseudomorphic high electron mobility

transistor (pHEMT), wideband, LNA that operates from 0.01 to 26.5

GHz. The ADL9005 provides a typical gain of 17.5 dB from 0.01

GHz to 14 GHz with a positive gain slope from 14 GHz to 20 GHz,

a 13.5 dBm typical output power at 1 dB compression (OP1dB)

from 0.01 GHz to 20 GHz, a 2.5 dB typical noise figure from 0.01

GHz to 14 GHz, and a typical output third-order intercept (OIP3) of

26 dBm from 0.01 GHz to 14 GHz, requiring only 80 mA from a

5 V supply voltage. The saturated output power (PSAT) of up to 16

dBm enables the LNA to function as a local oscillator (LO) driver

for many of Analog Devices, Inc., balanced, inphase/quadrature

(I/Q) or image rejection mixers. The ADL9005 also features inputs

and outputs (I/Os) that are internally matched to 50 Ω, making it

ideal for surface-mounted technology (SMT)-based, high capacity

microwave radio applications.

The ADL9005 is housed in a RoHS-compliant, 4 mm × 4 mm,

LFCSP.
