Abstract: An amplifier mixer device includes an amplifier structure having at least one amplifier input and at least one amplifier output. At least one of the amplifier outputs is looped back via a feedback to at least one of the amplifier inputs. The amplifier structure includes a mixer structure. The mixer structure comprises at least one switch having a switch input communicatively connected with the radio input, and a switch output communicatively connected with the mixer output. The switch input and switch output in a conducting state of the switch are electrically connected with each other and in a non-conducting state of the switch are electrically substantially not connected with each other. In use, the switch is switched from the conducting state to the non-conducting state and vice versa with the local oscillator signal.

Abstract: A frequency divider device includes a divider input and a phase count and select section. The phase count and select section includes at least two phase count and select inputs each communicatively connected to the divider input (for receiving each at least one phase shifted signal having a phase difference with respect to the other phase shifted signal); a signal generator section (for generating an output signal); a switch device; an inverter device; a counter device; and, a switch actuator device.
