Abstract
A radio frequency (RF) transmission circuit includes an input stage, a current-mode mixer coupled to an output of the input stage, an attenuator coupled to an output of the current-mode mixer, and a matching network coupled to an output of the attenuator. The input stage, current-mode mixer, attenuator, and the matching network are configured in a series stack.
Claims23
A radio frequency (RF) transmission circuit comprising:
- an input stage;
- a current-mode mixer coupled to an output of the input stage;
- an attenuator coupled to an output of the current-mode mixer;
- and
- a matching network coupled to an output of the attenuator,
