Suited for 4G smartphone RF front-ends, the “Woodstock” 16-band Multi-Mode, Multi-Band (MMMB) Envelope Tracking (ET) reference design is capable of covering up to 16 frequency bands from 700 MHz to 2.7 GHz in a PCB area of less than 200 mm2. The reference design overcomes the energy efficiency and frequency band challenges faced by mobile operators and handset OEMs since the introduction of 4G
The Woodstock reference design a highly integrated solution for global 3G/4G terminals. Featuring a multi-mode, multi-band ET PA, a broadband 2.3 to 2.7 GHz ET PA, and an additional region- or operator-specific LTE ET PA, the design ensures maximum frequency band coverage and energy efficiency at minimal costs. By enabling handsets to operate on almost all worldwide 3G and 4G bands, Nujira's new reference design significantly reduces the need for numerous regional product variants.
The Woodstock design integrates the company's NCT-L1200 Envelope Tracking supply modulator with PA devices, switches and filters from a number of Tier 1 suppliers. The ET modulator enables the handset to deliver full power to the antenna port, maximizing coverage and boosting data rates, even for LTE signals with high Peak-to-Average Power Ratios (PAPR), eliminating the need for Maximum Power Reduction (MPR). The NCT-L1200 ETIC has the industry's lowest output impedance, enabling it to drive up to 4 PA devices in parallel without compromising performance, even on the highest bandwidth 20 MHz LTE channels, while cutting energy consumption by 35%. The design also includes several patented PCB and component-level innovations to maximize system performance.(Contact company for pricing and availability)
