Abstract
Systems, circuits, and methods for mixing signals are provided. An illustrative circuit may include mixer circuitry including multiple inputs and at least one output, where the multiple inputs are connected across a local oscillator. The circuit may further include a terminal Radio Frequency (RF) output circuitry that is isolated from the local oscillator, where the at least one output of the mixer circuitry is directly connected to an input of the terminal RF output circuitry. The circuit may further include terminal Intermediate Frequency (IF) output circuitry that is isolated from the local oscillator, where the at least one output of the mixer circuitry is directly connected to an input of the terminal IF output circuitry.

1-20. (canceled)
A circuit, comprising:
- mixer circuitry comprising multiple inputs, a first output, and a second output, wherein the multiple inputs are connected across a local oscillator;
- terminal Radio Frequency (RF) output circuitry that is isolated from the local oscillator, wherein the first output of the mixer circuitry is directly connected to an input of the terminal RF output circuitry;
- and
- terminal Intermediate Frequency (IF) output circuitry that is isolated from the local oscillator, wherein the second output of the mixer circuitry is directly connected to an input of the terminal IF output circuitry.
A system, comprising:
- a local oscillator;
- a mixer comprising a first input, a second input, a first output, and a second output, wherein the first input and the second input are both connected to the local oscillator;
- and
- one or more output circuits connected to the first output and the second output of the mixer, wherein the one or more output circuits are isolated from the local oscillator, and wherein the one or more output circuits extract one or both of Radio Frequency (RF) components and Intermediate Frequency (IF) components from the first output and the second output of the mixer.
A method, comprising:
- connecting a mixer across a local oscillator;
- connecting a first output circuit directly to a first output of the mixer;
- connecting a second output circuit directly to a second output of the mixer;
- enabling the first output circuit to extract Radio Frequency (RF) components from the first output of the mixer;
- enabling the second output circuit to extract Intermediate Frequency (IF) components from the second output of the mixer;
- and
- isolating both the first output circuit and the second output circuit from the local oscillator using passive components.
