The maximum modulation bandwidth is 230 MHz, broadband variable gain amplifiers whose outputs are summed. which can be reduced by adding external capacitors to limit the The separate gain controls for each amplifier are linear-in- noise bandwidth on the control lines. magnitude. If the two input RF signals are in quadrature, the vector multiplier can be configured as a vector modulator or as Both the RF inputs and outputs can be used differentially or a variable attenuator/phase shifter by using the gain control pins single-ended and must be ac-coupled. The impedance of each as Cartesian variables. In this case, the output amplitude can be VGA RF input is 250 to ground, and the differential output controlled from a maximum of +5 dB to less than ­30 dB, and impedance is nominally 50 over the operating frequency the phase can be shifted continuously over the entire 360° range. The DSOP pin allows the output stage to be disabled range. Since the signal paths are linear, the original modulation quickly to protect subsequent stages from overdrive. The
