- Contributes to Improving and Increasing Receiver Sensitivity -

Nisshinbo Micro Devices Inc. will start production of the NT1189, a low noise amplifier (LNA), for 5G (Sub 6) base stations from November 2022.

The NT1189 is a LNA for 5G (Sub 6) base stations. It contributes to improving and increasing receiver sensitivity thanks to both low-distortion and high-gain characteristics as well as low NF (noise figure) characteristics. By modifying an external circuit, a wide bandwidth from 3.3 GHz to 5.0 GHz can be supported. In addition, adoption of a small and thin package enables reducing mounting area in base stations with many components installed.

The construction of high-speed and large-capacity networks using 5G communication networks has become an essential for the spread of DX (Digital Transformation), which supports an information-oriented society.

Nisshinbo Micro Devices Inc. will release high-performance LNA products for 5G base stations to enhance the stability of 5G communication networks.

NT1189 (DFN1616-6-GD package)

Applications and Examples of Use

1. Applications
5G base stations (macro cells and small cells), CPE (Customer Premises Equipment), Local 5G, DAS (Distributed Antenna System)

2. Examples of Applications

* The NJG1817 is an optimal SPDT switch for equipment that requires high power specifications, such as 5G (Sub-6) base stations.

Features

1. Achieving Low-distortion, High-gain, and Low NF (Noise Figure)
This product achieves reduction in strong input interference waves when receiving thanks to its low-distortion characteristics (OIP3 = +37 dBm Typ.). In the n77/78 and n79 bands of 5G (Sub6), it contributes to improving and increasing receiver sensitivity of base stations such as small cells by achieving high-gain characteristics of 21 dB to 26 dB, and low NF of 0.48 dB to 0.63 dB in the bandwidth.

2. Assembled in Small and Thin Package
It is assembled in a small and thin 1.6 × 1.6 × 0.397 mm leadless package, which is ideal for base stations with many components installed. It contributes to reduction of mounting area.
