Overview

Features and Benefits

  • Low noise figure: 2.5 dB typical at 0.025 GHz to 10 GHz
  • Single positive supply (self biased)
  • High gain: 16.5 dB typical at 0.025 GHz to 10 GHz
  • High OIP3: 36 dBm typical at 0.025 GHz to 10 GHz
  • RoHS-compliant, 2 mm × 2 mm, 6-lead LFCSP

Product Details

The ADL8121 is a gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), pseudomorphic high electron mobility transistor (pHEMT), low noise wideband amplifier that operates from 0.025 GHz to 12 GHz.

The ADL8121 provides a typical gain of 16.5 dB, a 2.5 dB typical noise figure, and a typical output third-order intercept (OIP3) of 36 dBm across the 0.025 GHz to 10 GHz frequency range, requiring only 95 mA from a 5 V supply voltage. The saturated output power (PSAT) of 21.5 dBm typical across the 0.025 GHz to 10 GHz frequency range enables the low noise amplifier (LNA) to function as a local oscillator (LO) driver for many of Analog Devices, Inc., balanced, in-phase and quadrature (I/Q) or image rejection mixers.

The ADL8121 also features inputs and outputs that are internally matched to 50 Ω, making the device ideal for surface-mounted technology (SMT)-based and is housed in a RoHS-compliant, 2 mm × 2 mm, 6-lead LFCSP.
