Automatic switching mid-sweep enables the use of multiple antennas when sweeping a wide frequency range.įor open source design files, visit the Opera Cake hardware directory in the HackRF github repository. Antenna switching works with the existing hackrf_sweep feature, which can sweep the whole tuning range in less than a second. Opera Cake also enhances the HackRF One’s use as a spectrum analyzer. No changes are needed to the existing SDR software, but full control from the host is available.
When HackRF One is used to transmit, Opera Cake can automatically route its output to the appropriate transmit antennas, as well as any external filters, amplifiers, etc. Its recommended frequency range is 1 MHz to 4 GHz. 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. Opera Cake is an antenna switching add-on board for HackRF One that is configured with command-line software either manually, or for automated port switching based on frequency or time.
