Sky5® 5G NR n77/78 Diversity Receive Module

The SKY53761-11 is a highly integrated LNA filter module that enables users to support 5G New Radio (NR) bands in the 3.3 to 4.2 GHz frequency range. The SKY53761-11 is part of our Sky5® product portfolio. It utilizes the latest advanced SOI process technologies to achieve leading high-bandwidth, low noise figure (NF) LNA performance in a small package footprint.

SKY53761-11 integrated multi-mode, variable gain LNAs work with all 5G chipsets. The device also integrates all the required filtering to attenuate unwanted out-of-band blockers in adjacent and far-out frequency bands while maintaining very low insertion loss (IL) performance in the passband frequencies.

The SKY53761-11 is packaged in a small 2.8 × 2.6 × 0.7 mm (max), 21-lead surface-mount package. No external DC blocking capacitors are required on the RF paths as long as no DC voltage is applied.

The part can operate over the temperature range of - 30 °C to +85 °C. A
