Jual Radio HF SSB ICOM IC 7300

New technology is changing the way receivers are being designed and the IC-7300 is an industry first as an RF, Direct Sampling System is being used in an entry level HF radio. The ability to digitize RF before various receiver stages reduces the inherent noise that is generated in the different IF stages of a radio. We feel the performance of the ‘7300 will far exceed your expectations for a radio considered entry level.

Radio HF SSB ICOM IC 7300 merupakan teknologi baru mengubah cara penerima dirancang untuk Sistem Pengambilan Sampel Langsung digunakan dalam radio HF entry level. Kemampuan untuk mendigitalkan RF sebelum berbagai tahap penerima mengurangi noise bawaan yang dihasilkan dalam berbagai tahapan IF radio. Kami merasa kinerja ‘7300 akan jauh melebihi harapan Anda untuk level entri radio.

Daya Output: 100W (25W AM)
Frekuensi RX: 0.030-74.800
Tipe Receiver: Direct sampling

ICOM IC 7300 IC-7300 menggunakan sistem pengambilan sampel langsung RF, di mana sinyal RF langsung dikonversi ke data digital. Kemudian diproses dalam FPGA (Field-Programmable Gate Array), sehingga memungkinkan untuk menyederhanakan konstruksi rangkaian serta mengurangi kebisingan yang dapat menutupi sinyal lemah. “IP +” baru meningkatkan kinerja titik intersep urutan ketiga (IP3) meningkatkan kemampuan untuk menyalin sinyal lemah yang berdekatan dengan sinyal interferensi kuat. Dalam proses ini, konverter A / D dioptimalkan untuk mengurangi atau menghilangkan distorsi sinyal.
