Low-Power RF Module Designs
To achieve such low-power multi-standard modules in such densely packed form factors at such high frequencies takes a new class of RF design tool. For this, we have created the Cadence® Virtuoso® RF Solution, for co-design of RFIC, package, and module substrates, using a free mix of GaAs, GaN, and Si transceiver technologies, and utilizing a suite of class-leading electromagnetic and circuit solvers.
For initial 5G rollout utilizing existing 4G infrastructure, i.e., 5G NSA (non-standalone), handset data will be 5G and control will be 4G. Potential harmonic interference between the two standards must be addressed through careful filter and power amplifier (PA) design. 5G PA design needs integrated envelope tracking, average power tracking, and back off to maximize handset battery life and the linearity demanded by dense 5G modulation schemes. To address this, the Spectre® X Simulator provides fast simulation speeds and golden accuracy with up to 10X performance improvement.
The Cadence Low-Power Solution ensures power minimization for handset 5G module IC design. This comprehensive solution encompasses architecture optimization, power estimation and analysis, functional verification, implementation and signoff, and IP for digital and mixed-signal designs at both the chip and system level.
Designers can conduct thermal analysis and electromagnetic analysis of the RF module with Cadence electromagnetic solutions and Cadence thermal solutions.
The new 5G capabilities also require new high-performance, low-power digital blocks such as beamforming engines, channelizers, and signal conditioners. These highly algorithmic blocks are naturally modeled in C++ or SystemC®, which Cadence Stratus™ High-Level Synthesis (HLS) synthesizes to highly efficient low-power RTL for implementation with the Cadence Low-Power Solution. Moreover, with Stratus HLS, these same algorithmic blocks can be retargeted for other 5G applications with different requirements, ranging from ultra-Iow-power IoT sensors to high-performance basestations.
Tensilica IP
For digital baseband precoding/combining, beam measurement, and tracking in the 5G transceiver design, Cadence provides the Tensilica® ConnX B20 DSP IP, utilizing the latest Tensilica NX architecture for the 10Gbs and above data rates needed for 5G.
