Chuck KutzEVLA Front-End CDR – LO/IF System April 24, FE to LO/IF Overview Mapping of broadband IFs to digitizer bandwidths. Signal flow from RF to baseband. Gain Slope Equalization Tuning capability

Chuck KutzEVLA Front-End CDR – LO/IF System April 24, IF Mapping (T303 Operation) If the frequency range of the “wanted” input IF is not within the 8 to 12 GHz range, then the IF is down converted using the other first LO synthesizer. For the Ku-band front end, both of the first LO synthesizers are used to down convert the IFs to X-band. Note: Any converted IF will be spectrally inverted from the non-converted IF.

Chuck KutzEVLA Front-End CDR – LO/IF System April 24, T304/305 Gain Slope Equalization The gain slope equalizers incorporated into this module, will be able to correct for passband slopes encountered in the front ends, downconverters, cables, etc. The amount of correction to be applied, will be determined by using the autocorrelation spectrum of the Widar correlator. There are 16 settings from a +15dB slope to a -15dB slope in 2dB steps. Analog equalization scheme used in order to accommodate the 3 bit digitizers.
