Sumitomo Electric: Commencing Sample Shipment of All-in-One RF Modules for LTE Base Station for Small Cells
Sumitomo Electric Industries, Ltd. (News - Alert) (TOKYO:5802) (ISIN:JP3407400005) has
recently commenced sample shipment of "TPM-2606P2" all-in-one Radio
Frequency (RF) modules for Long Term Evolution (LTE (News - Alert)) base station for
small cells. These modules are expected to dramatically shorten LTE base
station development and production periods.

With the recent spread of smartphones and other mobile devices, mobile
phone system traffic is increasing dramatically. As a promising means
for coping with the above situation, operators have started to use small
cells that can exclusively cover small areas where traffic is
concentrated. Sumitomo Electric has developed an all-in-one RF module
that can be used in a LTE base station for a small cell, on the basis of
the technology for the remote radio heads*1 that have already
been commercialized. The company has started sample shipment of the new
RF module.
The all-in-one RF module "TPM-2606P2," is intended for use in a 2.6
GHz-band TD-LTE*2 base station which will become widely used
in future. All RF circuits (transmitter amplifier, receiver amplifier
and transmitter/receiver switch) essential to construct a base station
are compactly modularized. Use of the new RF module will dramatically
shorten base station development and production periods and simplify the
introduction of small cells.

[Advantages of Sumitomo Electric all-in-one RF module "TPM
2606P2"]
|
|
1.
|
|
Transmitter amplifier
|
|
|
|
The Doherty-type amplifier*3 used in the amplifier
enhances the power utilization efficiency to 40% or more (when
outputting 6 W LTE signals).
|
|
2.
|
|
Receiver amplifier
|
|
|
|
The balanced amplifier*4 used in the amplifier achieves
low-noise, high input power tolerance together with low reflectance
properties of the antenna port.
|
|
3.
|
|
Transceiver/receiver switch
|
|
|
|
A combination with a circulator*5 lowers switching loss
and application power, thereby enhancing the switching reliability.
|
|
4.
|
|
Distortion compensation circuit
|
|
|
|
The new RF module comprises a circuit that can compensate for
distortion that occurs in the transmitter amplifier, thereby
eliminating the necessity for additionally installing an expensive
distortion compensation circuit outside the module. This module
design also frees the production department in charge from such
problems as non-compliance of the combination of the amplifier and
distortion compensation circuit with the applicable standards.
|
In addition to this RF module, the company is advancing the development
of RF modules for 2.6 GHz band FDD-LTE*6 and 3.5 GHz band
TD-LTE. Different transmission powers and frequencies are available on
request. For further information, please contact us.
