<p>The present invention discloses active unit cell topologies for quasi-optic grid array structures that make use of combinations of one of several broadband or frequency-selective positive (or regenerative) feedback networks, as well as multiple transistor configurations in order to enhance the gain of the grid array amplifier. These new topologies yield higher gain, extending the utility of the grid array amplifier to both new applications requiring higher gain, as well as to higher frequencies where the intrinsic gain of the active devices is lower. They also offer greater flexibility in impedance matching, improving the bandwidth and manufacturability of the design.</p> |
