<p>A complex RF weighter provides an RF output signal controlled in amplitude and phase with respect to an input signal. The input signal is applied to a quadrature hybrid (14) that is terminated with two PIN diodes (16, 18), one of which is one-eighth wavelength farther from the hybrid than the other. Independent control of the bias (38) on the PIN diodes (16, 18) provides control of the relative amplitude and phase of the output signal. </p> |
