Qualcomm, along with a new modem Snapdragon X55 5G announced the establishment of solutions with the input RF-module (RFFE) second generation mobile multimodal 5G. New products allow you to create complex systems "from the modem to the antenna" for high-end mobile devices 5G, supporting the lower frequency bands 6 GHz and millimeter wave spectrum.
This system solution is developed in order to simplify and reduce the cost for the manufacturers the task of creating 5G end devices with improved performance in terms of the growing number of frequency bands and the need to support multi-mode operation from 2G to 5G. The company notes, that mobile operators in the propagation of these solutions benefit from the improved capacity and coverage, and consumers get thinner 5G smartphones with improved autonomy, reliable communication, Quality and bit rate.
Qualcomm believes, that supply modems and RF-solutions alone is not sufficient, and because it offers an integrated approach "from the modem to the antenna", trying to be the first in the implementation of all aspects of support 5G.
Among the recently announced solutions RFFE present millimeter wave antenna module Qualcomm QTM525 5G, which has reduced compared with the first generation height, thus it can be applied in a thickness of less than 5G smartphones 8 mm. The module supports a new range of n258 (26 GHz) North America, Europe and Australia in addition to the former n257 (28 GHz), n260 (39 GHz) and n261 (28 GHz for US).
New and improved solutions RFFE power amplifier and spaced reception include Qualcomm:
- Power amplifier modules, are compatible with QET6100 to support the tracking of the envelope in the range of 5G 100 MHz. QPM6585, QPM5677 and QPM5679 for n41 ranges, n77 / n79 and 78 respectively.
- Average- and high-frequency module 5G / 4G PA QPM5670, having a built-in low noise amplifier (LNA), switch, filters and 5G geksaplekser.
- Low-frequency module PA 5G / 4G QPM5621 with integrated LNA, switches and filters, combining support carrying the low frequency range and the possibility of double compounds.
- The family of modules spaced reception QDM58xx, equipped with built-in LNA 5G / 4G, switches and filters, with support for a range of MIMO below 6 GHz.
In order to help producers cope with the increasing number of antennas and ensure that the work of frequency bands, required for mobile devices, Qualcomm introduced antenna and tuner signal amplification QAT3555, which expands the range of adaptive adjustment of the antenna to the 5G 6 GHz, at the same time 25 % reducing the height of the body and reducing losses.
Experimental batches of the product becomes available to interested partners Qualcomm in the first half of the year, and mass production of commercial end-devices will take place towards the end of 2019 of the year.
