ADL5205 - 1 dB Step Size DGA

General Description

The ADL5205 is a digitally controlled, wide bandwidth, variable gain dual amplifier (DGA) that provides precise gain control, high output third-order intercept (OIP3) and a near constant noise figure for the first 12 dB of attenuation.

Key Features

  • Dual, independent, digitally controlled gain amplifier (DGA).
  • 9 dB to +26 dB gain range 1 dB step size, ±0.2 dB accuracy at 200 MHz 100 Ω differential input resistance 10 Ω differential output resistance 1.2 dB change in noise figure for first 12 dB of gain reduction Output third-order intercept (OIP3): 48.5 dBm at 200 MHz, 5 V, high performance mode.
  • 3 dB bandwidth: 1700 MHz typical in high performance mode Multiple control interface options Parallel 6-bit control interface with.
