It has two primary ports, each connected to any of eight secondary ports, and is optimized for use as a pair of 1x4 switches or as a single 1x8 switch. Its recommended frequency range is 1 MHz to 4 GHz.\u003c\/p\u003e\n\u003cp\u003eWhen HackRF One\/Pro is used to transmit, Opera Cake can automatically route its output to the appropriate transmit antennas, as well as any external filters, amplifiers, etc. No changes are needed to the existing SDR software, but full control from the host is available.\u003c\/p\u003e\n\u003cp\u003eOpera Cake also enhances the HackRF One\/Pro’s use as a spectrum analyzer across its entire operating frequency range of 1 MHz to 4 GHz. Antenna switching works with the existing hackrf_sweep feature, which can sweep the whole tuning range in less than a second. Automatic switching mid-sweep enables the use of multiple antennas when sweeping a wide frequency range.\u003c\/p\u003e\n\u003ch2\u003eDownloads\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/hackrf.readthedocs.io\/en\/latest\/opera_cake.html\" target=\"_blank\"\u003eDocumentation\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/greatscottgadgets\/hackrf\/tree\/master\/hardware\/operacake\" target=\"_blank\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Great Scott Gadgets","offers":[{"title":"Default Title","offer_id":46907279671628,"sku":"20083","price":199.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/6280\/3788\/files\/great-scott-gadgets-opera-cake-antenna-switch-for-hackrf-one20083-422666.jpg?v=1718724568","url":"https:\/\/www.elektor.com\/products\/great-scott-gadgets-opera-cake-antenna-switch-for-hackrf-sdr","provider":"Elektor","version":"1.0","type":"link"}
