Menlo’s MM5120 comes at the heels of decades of development on the Ideal Switch platform. This innovative technology enables robust and highly reliable switches capable of >25 W CW power handling at 6.0 GHz. The MM5120 provides ultra-low insertion loss and superior linearity from 18 GHz down to DC, with >3 billion switching cycles guaranteed. For its small size and high reliability, the MM5120 is the obvious choice for replacing large RF electromechanical relays but it’s also an ideal alternative for RF/microwave solid-state switches in applications where linearity and insertion loss are paramount.
Wideband, High Frequency Switch Enables 5G mmWave Design
Additionally, Steven is mentioning one of the most interesting parts released in 2022, the 9kHz to 67GHz CMOS SOI SP4T switch from pSemi. Supplier Business Manager Steven Darrow wanted to highlight this unique entry into mmWave components due to its super low latency at a switching speed of just 75nS, exceptional power handling and linearity, and of course, its unparalleled wideband performance up to 67GHz. 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.
Knowles B259MC1S Band Pass Filter for n258 Band
RFMW Supplier Business Manager of Passive Divisions, Nick John, has selected Knowles’ B259MC1S microstrip bandpass filter as a noteworthy component of 2022. Using high-K ceramic materials, the B259MC1S offers highly repeatable performance without tuning. Complete with integrated shielding, this SMT device is designed for use on most RF PWB materials for mmWave applications. Its frequency of 24.25 to 27.5 GHz remains stable over temperatures ranging from -55°C to +125°C. The B274MB1S is designed for demanding/high-reliability and 5G Telecom applications.
Renesas’ F6212, 16-Channel Dual-beam Rx Active Beamforming IC Module for Ka-Band SATCOM
Nick has also highlighted the Renesas F6212 as one of his top products of 2022. The F6212 is a 16-channel, dual-beam, receive active beamforming, RFIC multi-chip module designed for applications in Ka-Band SATCOM planar phased array antennas.
