  • Abstract
    The first complete 70 GHz back end module (BEM) of the coming Planck satellite is described. It includes an H-plane waveguide band pass filter, an InP HEMT amplifier, a diode detector made on 0.1 mm alumina substrate, and video amplifiers. RF parts are designed, manufactured, and measured individually and then the complete BEM is tested. Stringent requirements are set through the mechanical layout of the entire functional unit. Most specifications have already been met with the exception of conversion loss in band ripple which must be further reduced.
