60 GHz RF signal goes via a band-pass filter to the output connector of the SQM.

From the SQM, the 40 to 60 GHz RF output signal goes to input connector J1 of the forward coupler, P/N C27184. The other input to the forward coupler at connector J2 is the 0.01 to 40 GHz (0.5 to 40 GHz for 682X5B/683X5B models) RF output signals from the SDM. From forward coupler output connector J3, the 0.01 to 60 GHz (0.5 to 60 GHz for the 682X5B/683X5B models) RF output signals go to the directional coupler.

65 GHz Models (SQM P/N 60-142)

During CW or swept frequency operations in the 40 to 65 GHz frequency range, the 10 to 16.25 GHz RF signal input is quadrupled and amplified, then goes to the modulator. The modulator provides for power level control and amplitude modulation of the RF output signal. From the modulator, the 40 to

65 GHz RF signal goes via a band-pass filter to the output connector of the SQM.

Power Level The RF signal output from either the switched filter

Detection/ assembly (￿20 GHz models), the SDM (￿26.5 GHz or

ALC Loop ￿40 GHz models), or forward coupler (>40 GHz mod- els) goes to the directional coupler for transfer to the RF OUTPUT connector. A portion of the RF output signal is detected, amplified, and coupled out as feedback to the ALC circuitry on the A10 ALC PCB. In these circuits, the signal from the detector is summed with the reference voltage that represents the desired RF output power level. The resulting voltage is fed from the A10 ALC PCB to the ALC modulator driver circuit on the A9 PIN Control PCB (and the ALC modulator driver circuit on the A14 SDM, SQM Driver PCB for >40 GHz models). The resulting modulator control signals go to the modu- lators in the switched filter assembly, the SQM (for >40 GHz models), and the digital down converter
