AD8340 - RF Vector Modulator

General Description

The AD8340 vector modulator performs arbitrary amplitude and phase modulation of an RF signal.

Because the RF signal path is linear, the original modulation is preserved.

This part can be used as a general-purpose RF modulator, a variable attenuator/phase shifter, or a remodulator.

Key Features

  • Cartesian amplitude and phase modulation 700 MHz to 1.0 GHz frequency range Continuous magnitude control of.
  • 2 dB to.
  • 32 dB Continuous phase control of 0° to 360° Output third-order intercept 24 dBm Output 1 dB compression point 11 dBm Output noise floor.
  • 149 dBm/Hz at full gain Adjustable modulation bandwidth up to 230 MHz Fast output power disable 4.75 V to 5.25 V single-supply voltage.
