Overview
The RML-N1 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-N1 supports NR FR1(sub6) n2/ n5/
n12/ n25/ n30/ n41/ n66/ n71/ n77, LTE Band 2/ 4/ 5/ 12/ 25/ 26/ 30/ 41/ 48/ 66/ 71, LTE Band 29/46 is for downlink only.
The RML-N1 devices also have an internal GPS receiver that can operate standalone or in simultaneous operation with its
WWAN radios.
The RML-N1 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-N1 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-N1 supports both FDD and TDD mode, MIMO capability: up to 4x4 DL MIMO, and 2x2 UL MIMO for
n41. 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
