Signal detection demostration at university for my thesis project documentation.
Nominal frequency: 2230.800MHz (telemetry). Signal detected 15dB over noise (1Hz BW) with strong doppler shift.
Antenna: Ex-Inmarsat 1.2m collapsible mesh dish feeded with 3.5turns LHCP helix.
LNA: 0.6dB NF 15dB gain amplifier with ATF-36077 GaAs Fet on TLY-5A homemade pcb.
Downconverter: S-Band synthesized frecuency converter (thesis project). 1.5dB NF, 30dB Gain, excelent properties. 435MHz IF.
SDR Downconverter: 435 to 10.7MHz done by AOR AR3000A modified general coverage receiver.
Software Defined Radio: RFSpace SDR-IQ used as FFT analyzer.
