The present invention provides systems and methods for temperature-controlled ablation using radiometric feedback. An interface module may include (a) a processor (b) a first input/output (I/O) port to receive digital radiometer and digital thermocouple signals from an integrated catheter tip (ICT) (c) a second I/O port to receive ablative energy from a generator (d) a temperature display (e) a patient relay (f) a computer-readable medium storing instructions for causing the processor to: (i) calculate a temperature adjacent to the ICT based on the digital radiometer and thermocouple signals and operation parameters (ii) cause the temperature display to display the calculated temperature and (iii) close the patient relay to pass ablative energy received on the second I/O port to the first I/O port and (g) a temperature control subsystem to regulate the ablative power based on the calculated temperature.
