Abstract :
A device on a single 2"-LaAlO/sub 3/ wafer for a four bit instantaneous frequency measurement between 9.5 GHz and 10.5 GHz has been developed with coplanar YB/sub 2/Cu/sub 3/O/sub 7-/spl delta// delay lines and power dividers. Compared to known triplate strip lines, coplanar delay lines are easier to fabricate monolithically and allow for a greater flexibility in the circuit design. Simulated and measured results are in good agreement.<>
