Abstract
Embodiments herein describe an integrated circuit with a digital front end (DFE) that includes multiple hardened mixers that can be configured to support multiple different radio paths. The DFE provides the ability to distribute the processing across the multiple mixers, which can be combined and synchronized to create a larger mixer or may be used in other combinations to create multiple discrete mixers.
Claims20
A digital front end (DFE), comprising:
- first and second mixers implemented in hardened logic, each comprising a plurality of subunits;
- and
- circuitry configured to form inter-mixer communication paths connecting at least one of the plurality of subunits in the first mixer to at least one of the plurality of subunits in the second mixer,
- wherein the first and second mixers are configured to, when operating in a downlink (DL) path of a radio, synchronously operate to effectively form a single, larger mixer using the inter-mixer communication paths.

A DFE, comprising:
- first and second mixers implemented in hardened logic, wherein the first and second mixers are configured to synchronously operate to effectively form a first larger mixer for use in a downlink (DL) path of a radio;
- and
- third and fourth mixers implemented in hardened logic, wherein the third and fourth mixers are configured to synchronously operate to effectively form a second larger mixer for use in an uplink (UL) path of the radio.
An integrated circuit, comprising:
- first and second mixers implemented in hardened logic, each comprising a plurality of subunits;
- and
- circuitry configured to form inter-mixer communication paths connecting a subset of the plurality of subunits in the first mixer to a subset of the plurality of subunits in the second mixer,
- wherein the first and second mixers are configured to, when operating in a downlink (DL) path of a radio, effectively form a single, larger mixer using the inter-mixer communication paths.
