A precision bipolar 5-6GHz band quadrature-phase generator

A wideband bipolar doubler and high-sensitivity regenerative divider with precise I-Q phase tuning via a dc bias control are described. Measurements in the 5-6GHz band demonstrate that negligible residual phase noise is added by the circuit, which has an active area of just 0.26/spl times/0.11mm/sup...

Summary:A wideband bipolar doubler and high-sensitivity regenerative divider with precise I-Q phase tuning via a dc bias control are described. Measurements in the 5-6GHz band demonstrate that negligible residual phase noise is added by the circuit, which has an active area of just 0.26/spl times/0.11mm/sup 2/, consumes 23mW at 2.7V and has a simulated phase tuning range of /spl plusmn/22/spl deg/ with 0.04/spl deg//mV sensitivity.
