WebBefore we go on, let's point out that a Lange coupler is a 3 dB microstrip coupler that accomplishes the required even/odd impedances for equal split. Julius Lange divided the lines into multiple smaller lines to provide … WebThis phase shift is both broadband (unlike a delay line) and relative (between the outputs). Marki quadrature hybrids are created by building a backwards wave coupler (similar to our stripline directional couplers) with a 3 dB coupling value and creating equal power outputs (for other methods and their merits or demerits, see this tech note).

The second broader-band design used balanced attenuators (see [2]), which are insensitive to switch parasitics. Each balanced attenuator consists of two complementary uncompensated switch attenuators connected by Lange couplers. A test chip (Fig. 2) was designed to evaluate both the narrowband and broadband vector modulator WebAn X-band high-efficiency MMIC power amplifier with 20-dB return losses. × Close Log In.
