Nisshinbo Micro Devices has launched the single pole double throw (SPDT) switch NT1819, designed for 5G infrastructure. It supports the sub-6 GHz band from 3.3 to 5.0 GHz and delivers isolation performance exceeding 60 dB within a 3.0 x 3.0 mm package.
This isolation performance reduces interference between adjacent components in 5G base stations, an advantage for applications such as digital predistortion signal combining. A built-in 50 Ω absorptive termination ensures impedance matching regardless of the switch state, which helps suppress signal reflection and improve system stability.
In addition to the isolation performance in the main 5G frequency bands, NT1819 features a frequency range from 0.2 to 7.125 GHz, insertion loss between 0.7 and 1.2 dB and a switching speed of 250 ns. It also operates reliably across a temperature range from -40°C to +105°C, ensuring performance in various deployment environments. With these attributes, this product is well-suited for a wide range of next-generation communication systems applications, including Wi-Fi and unlicensed communications in the U.S. Its packaging and performance support the miniaturization and integration trends guiding modern RF systems.
In addition to device supply, Nisshinbo offers advanced solution services for module manufacturing. These include bare-die mounting techniques that enable direct integration onto substrates or carriers, thus streamlining the production process and reducing space and cost.
