F1e - Wideband IQ Demodulator


Description

The F1e module is the wideband IQ version of the F1d module. It has the same IQ demodulator IC with the same RF range of 40 MHz to 1.4 GHz, but the output stage now has a bandwidth of 500 MHz (switchable to 200 MHz by software). This allows for the demodulation to non-zero IF or the downmixing of multiple resonators in one go. These can then be further demodulated in the digital domain by an FPGA or digitizer.
