Kami telah menyiasat operasi penambah isyarat-ke-bunyi gelombang magnetostatik jenis pantulan secara terperinci. Ia mempunyai ciri peningkatan yang baik, kehilangan sisipan yang rendah, dan kuasa operasi yang rendah. Ia juga terdiri daripada transduser menggunakan substrat seramik yang mempunyai pemalar dielektrik tinggi dan filem LaGa-YIG dengan kemagnetan tepu rendah untuk membolehkan operasi terus dalam jalur 400-MHz (jalur IF penerima DBS semasa). Peningkatan 8 dB telah dicapai melalui lebar jalur 40-MHz. Walaupun julat frekuensi operasinya bergantung secara kritikal pada suhu peranti, kami boleh mengimbangi pergantungan suhu dengan melaraskan medan magnet bias. Eksperimen menunjukkan bahawa penambah meningkatkan nisbah pembawa kepada hingar yang diterima sebanyak 2 hingga 3 dB, memberikan pengurangan hingar yang baik dalam penerimaan DBS.

Abstract: We have investigated the operation of a reflection type magnetostatic wave signal-to-noise enhancer in detail. It has good enhancement characteristics, low insertion loss, and low operating power. It is also composed of a transducer using a ceramic substrate having a high dielectric constant and an LaGa-YIG film with low saturation magnetization to enable direct operation in the 400-MHz band (the IF band of current DBS receivers). Enhancement of 8 dB was achieved over a 40-MHz bandwidth. Although its operating frequency range depends critically on device temperature, we can compensate for the temperature dependence by adjusting the bias magnetic field. Experiments showed that the enhancer improved the received carrier-to-noise ratio by 2 to 3 dB, providing good noise reduction in DBS reception.
