72 to 84 GHz, -100 dBm Rx Input Power, 4.5 dB Noise Figure, E Band Dual Channel Down Converter
Model SSK-SR723843-12-C1 is an E band, dual-channel down converter. The down converter takes a 72 or 84 GHz signal at -100 dBm power through an LNA to diplexers and X8 multipliers to reach 6 GHz through a narrow bandpass coax filter. Two stages of IF gain provide 70 dB of gain. The 6 GHz coaxial filter is implemented to clean any unwanted harmonic and spurious. The LO for the frequency conversion is 9.75 GHz. The down converter assembly has a nominal IF output power of 0 dBm and the conversion gain and noise figure of the receiver are 100 dB and 4.5 dB respectively. The down converter assembly requires +8 VDC/875 mA and +12 VDC/700 mA DC bias typically. The assembly uses WR-12 waveguides for the input RF and female SMA connectors for both LO and IF ports.
