This switch is ideal for test and measurement, 5G mmWave, microwave backhaul, radar and satcom, and countless other applications. Due to their patented UltraCMOS SOI process, pSemi has truly outdone themselves with the PE42545 by packing in so much performance and efficiency into such a small, flip chip die package.
Ultra Compact XBAW Filters for Wi-Fi 6E
RFMW Supplier Business Manager, Colin Field, is recommending Akoustis’ A10155 and A10165 XBAW filters for Wi-Fi 6E applications due to their high power, small size, and excellent rejection performance that enables the next generation of Wi-Fi access points. Shipping in volume to major OEM’s globally, the filter pair can be combined to allow the entire UNII 1 to 3 and UNII 5 to 8 bands to operate simultaneously–delivering more than 40dB of adjacent channel rejection. Akoustis has developed an entire portfolio of filters for various configurations of Wi-Fi 6E architecture that offer the broadest portfolio of BAW technology solutions on the Wi-Fi market today. With more product launches coming in early 2023 for next generation W-iFi 7, it’s an exciting time for the Akoustis product line.
Small Form Factor Filters for Satcomms
Colin has also selected Cubic-Nuvotronics’ PSF39B04S cavity filter as one of his top product picks of 2022 due to its small form factor and high power capability. Designed for Downlink applications in V band Satcomm systems, the filter supports 4GHz of V band spectrum, an important segment of licenced spectrum that enables higher data rates for LEO communications applications. The filter utilizes a unique fabrication process enabling micron-level feature accuracy, which in turn leads to sharper filter responses with smaller footprints. The copper substrate that the PSF39B04S incorporates ensures excellent thermal conductivity for higher power applications. Its compact 6mm x 3.5mm footprint enables its use in phased array applications. The filter has 2.2dB of insertion loss, reducing the demand on power-hungry gain blocks. Additionally, Colin notes that Cubic-Nuvotronics’ filters can be designed for customer-specific applications.
