This course is day 4 of the LTE, LTE-Advanced and HSPA Evolution: System Design and Operation course and can be taken on its own or as part of the 5-day course. For details of the full 5-day LTE, LTE-Advanced and HSPA Evolution: System Design and Operation course click here.
With the explosion of frequency bands and band combinations, balancing the radio performance, hardware cost and total power consumption in the multi-mode multi-standard poses serious design challenges.
This session presents an overview of solutions and strategies put in place by chipset platform vendors to deliver cost efficient HPSA+, LTE and LTE-advanced terminals, with a focus on the radio-frequency (RF) subsystem and RF- Front-End (RF-FE) architectures.
We introduce modern transmitter and receiver chain RF architectures in detail, including co-existence scenarios within the numerous subsystems of the multi-band / multi-mode “world- wide” phone.
From a power consumption perspective, the modern smartphone performance is compared to the more traditional, voice centric feature phone. Design challenges in delivering the best compromise between performance and power consumption is briefly presented for two dominating contributors: Application Engine and cellular Power Amplifier, comparing average power tracking vs. envelope tracking.
A brief presentation of progress made in reducing power consumption across three recent generations of LTE chipset is also presented. Finally, we describe some of the specific challenges associated with the implementation of LTE-Advanced carrier aggregation platforms.
Introduction to Multimode Multiband handset design challenges- 3GPP frequency band evolution vs year vs mode and typical handset band support
- Worldwide phone frequency band requirements: dual-mode, vs triple-mode vs quad-mode
Cost reduction in Multimode Multiband terminals- Evolution of Silicon Area and component count in single mode (GSM), dual-mode (GSM-HSPA), triple mode (GSM-HSPA-LTE) terminals
- RF transceiver architecture: 10 years of evolutions to reduce PCB area and component count
- Solving the cost-performance trade-off by removing interstage SAW filters
- Carrier-Aggregation (CA) challenges: impact on complexity and TX noise requirements
- Trends in filters and RF switches over the last 10 years
- Front-end Module integration evolution in recent smartphones
- RF multiplexing strategies to address CA: duplexer bank vs quadplexers vs hexaplexers
- Example of trade-offs applied to a North-American triple mode design
- Reconfigurability concept with MMMB PA modules
- Cost savings: discrete PA vs MMMB PA in triple mode NA variant example
- WCDMA TRP TIS smartphone performance status
- OTA performance challenges with MIMO operation
- Antenna tuner & impedence tuner: cost performance trade-offs
- Example of cost savings using MIPI DigRF v4 and RFFE on a Carrier Aggregation RF subsystem

- Other co-existence associated with LTE operation
Power consumption reduction in MM MB terminals
- Benchmark of recent triple mode chipsets
