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. The amplitude can be controlled from a maximum of ?2 dB to less than ?32 dB, and the phase can be shifted continuously over the entire 360° range. For maximum gain, the AD8340 delivers an OP1dB of 11 dBm, an OIP3 of 24 dBm, and an output noise floor of ?149 dBm/Hz, independent of phase. It operates over a frequency range of 700 MHz to 1.0 GHz.
