The apparatus of 50, wherein the suspended element extends between the first and second mounting shelfs along a longitudinal direction of the mixer apparatus.
A detector apparatus, comprising:
- one or more mixers;
- one or more feedhorns coupled to a radio frequency (RF) input of at least one of the mixers;
- a local oscillator coupled to a local oscillator (LO) input of the at least one mixer;
- an output channel coupled to an intermediate frequency (IF) output of the at least one mixer;
- and
- one or more of a low noise amplifier, power detector, and analog-to-digital converter connected to the output channel and configured to process an output IF signal from the at least one mixer,
- wherein the at least one mixer comprises:
- a suspended signal transmission element comprising a plurality of suppression slots and one or more filter elements;
- and
- a diode circuit mounted on the suspended signal transmission element.
