Limesdr vs hackrf9/16/2023 ![]() Also you can use custom made downconverter and high performance short wave DDC receivers such as RedPitaya SDRlab 122-16 to capture wide bandwidth downconverted from 2 GHz to a short wave band. ADALM-PLUTO has RF coverage from 325 MHz to 3.8 GHz (can be hacked to work from 70 MHz) with up to 20 MHz of instantaneous bandwidth. LimeSDR is full-duplex, MIMO, and superior to BladeRF. You could buy an Ettus USRP B200 or B210 for around 1,216, A bladeRF x40 for 420, or a LimeSDR for 299. Ebay has tons of Chinese sellers who advertise these for very cheap(around 15). For LTE frequecy bands (1800-2100 MHz) I would suggest ADALM-PLUTO: It has 12 bit ADC/DAC and FPGA processing, so you can look at it as upgraded HackRF with 12-bit ADC/DAC. However, this can be done by buying a cheap external clock that plugs into the HackRF board inputs. ![]() HackRF is better, it is classic 8-bit DDC. The performance of RTLSDR and SDRPlay is much worse than classic 8-bit DDC receiver. But they all are low performance budget level receivers. If you choose between RTLSDR, SDRPlay and HackRF, I would suggest HackRF. Because RTLSDR has more predictable behavior, less spurs and no gaps in a frequency coverage. If you choose between RTLSDR and SDRPlay, I would suggest RTLSDR. ![]() Actually it has 12-bit ADC, but it's spectral purity of LO synthesizer is worse than RTLSDR, so you won't get advantage in average. "14 bit" is a marketing for processing gain. In some cases it can be a little better, but it's LO has spectral purity issues and RF tuner limitations. SDRPlay provides almost the same performance as 8 bit RTLSDR.
