Pengganding jalur mikro kearah tinggi yang menekan gandingan kebocoran dengan litar pembatalan pembahagi Wilkinson dibentangkan. Pengganding yang dibentangkan menggunakan litar pembatalan antara port gandingan dan port pengasingan pengganding jalur mikro konvensional untuk meningkatkan pengasingan. Litar pembatalan terdiri daripada pembahagi Wilkinson, atenuator berbilang peringkat, dan garisan ofset fasa. Kekerapan untuk meningkatkan pengasingan dikawal oleh attenuator. Oleh kerana arahan dipertingkatkan tanpa pengubahsuaian pengganding konvensional, litar pembatalan boleh digunakan pada pengganding konvensional yang direka. Directivity yang diukur bagi pengganding 1/18 λ yang dipersembahkan dipertingkatkan daripada 4.8 dB kepada 43.0 dB pada 2.6 GHz, berbanding dengan pengganding 1/4 λ konvensional dengan gandingan -20 dB. Pada masa yang sama, lebar jalur relatif 27.4% dengan arahan 20 dB dicapai.

Abstract: A high directivity microstrip coupler suppressing leak coupling with a cancellation circuit of a Wilkinson divider is presented. The presented coupler utilizes a cancellation circuit between a coupling port and an isolation port of the conventional microstrip coupler to enhance the isolation. The cancellation circuit consists of the Wilkinson divider, the multistage attenuator, and the phase offset line. The frequency to enhance the isolation is controlled by the attenuators. As the directivity is improved without the modification of the conventional coupler, the cancellation circuit can be applied to the fabricated conventional couplers. The measured directivity of the presented 1/18 λ coupler is improved from 4.8 dB to 43.0 dB at 2.6 GHz, compared with the conventional 1/4 λ coupler with -20 dB coupling. Simultaneously, the 27.4% relative bandwidth with the 20 dB directivity is achieved.
