1 Overview
The RML-N1v devices are WWAN LGA module in size 45x45mm. The LGA module and device software combination deliver
multiband, multimode WWAN connectivity in a single hardware configuration. RML-N1v supports NR FR1(sub6) n2/ n5/ n66/ n77,
LTE Band 2/ 5/ 12/ 13/48/ 66. The RML-N1v devices also have an internal GPS receiver that can operate standalone or in
simultaneous operation with its WWAN radios.
The RML-N1v device uses Mediatek chipset components. It implements the 5G NR standard for sub-6 GHz bands. The MT6190
device is a highly-integrated multimode, multiband RF CMOS transceiver IC that interfaces with the MT6890 device through IQ
interface, it is the integrated single-chip RFIC that supports 5G NR sub-6 together with legacy 3G to 4G LTE.
RML-N1v and supported features for the NR FR1, Duplex mode: FDD(Frequency Division Duplex) and TDD((Time Division
Duplex)). MIMO(Multi-input Multi-output) capability: up to 4x4 DL MIMO; CA(Carrier Aggregation) capability: DLCA: inter-
band, intra-band contiguous and intra-band non-contiguous DLCA; ULCA: inter-band and intra-band contiguous ULCA.
Modulation: UL: 256QAM; DL: 256QAM. Waveform: UL: CP-OFDM and DFT-S-OFDM; DL: CP-OFDM.
As for LTE, RML-N1v supports both FDD and TDD mode, MIMO capability: up to 4x4 DL MIMO, and 2x2 UL MIMO. CA
capability: DLCA: inter-band, intra-band contiguous and intra-band non-contiguous DLCA; ULCA: inter-band and intra-band
contiguous ULCA. Modulation: UL: 256QAM; DL: 256QAM
