GENERAL DESCRIPTION

The AD8341 vector modulator performs arbitrary amplitude and phase modulation of an RF signal.

Since the RF signal path is linear, the original modulation is preserved. This part can be used as a general-purpose RF modulator, a variable attenua tor/phase shifter, or a remodulator.

The amplitude can be controlled from a maximum of ?4.5 dB to less than ?34.5 dB, and the phase can be shifted continuously over the entire 360° range.

For maximum gain, the AD8341 delivers an OP1dB of 8.5 dBm, an OIP3 of 17.5 dBm, and an output noise floor of ?150.5 dBm/Hz, independent of phase. It operates over a frequency range of 1.5 GHz to 2.4 GHz.
