The NT1821 is specifically designed for wireless communication systems, with a particular emphasis on Wi-Fi 7 applications.
It supports functions like transmit/receive switching and antenna switching. It covers a frequency range from 1.0 to 7.125 GHz and offers high isolation, making it an ideal solution for advanced wireless networks.
It has an operating voltage range from 1.6 to 5.0 V and with a control voltage down to 1.2 V.
Key performance metrics include low insertion loss, and high linearity with a P-1dB of +31 dBm.
Applications for the NT1821 include 802.11a/b/g/n/ac/ax/be networks, Wi-Fi modules, smartphones, access points, and other mobile devices.
With integrated DC blocking capacitors on all RF ports, the NT1821 is optimized for minimal PCB space and simplified system design.
The typical isolation at higher frequencies (up to 7.125 GHz) reaches 42 dB, while maintaining low insertion loss values across the entire frequency range.
Recommended operating conditions ensure reliability between -40 °C and +105 °C, and has operating currents as low as 20 μA.
The NT1821 and NT1822 are identical devices, but have opposite control voltages for the VCTL pin.
The 1.0 × 1.0 mm DFN1010-6-GV package is designed to save PCB space, making it ideal for Wi-Fi modules, access points, smartphones, and other mobile devices.
The device has an MSL1 rating; components in this category have the lowest sensitivity to moisture and can be exposed to ambient air without special precautions. Furthermore, it is RoHS compliant and halogen-free, meeting environmental standards.
The NT1821 and NT1822 are available for purchase now.
