Akoustis Introduces 3.8 GHz BAW RF Filter for Radar Applications

Akoustis Technologies has introduced a new high frequency BAW RF filter product for 3.8 GHz radar applications. The AKF-1938 Filter is the result of a key customer collaboration with a well-established OEM specializing in non-mobile communication systems with annual revenue of more than $1 billion. Akoustis expects to offer pre-production packaged product samples later this quarter.

The AKF-1938 is a high performance, ultra-small passband 3.8 GHz BAW RF filter designed for use in radar and RF transceiver applications. The filter wafers will be manufactured using Akoustis’ new proprietary XB1 single-crystal BAW manufacturing process, which delivers high-performance RF filter solutions for frequencies up to 7 GHz. It provides a low insertion loss covering 100 MHz of bandwidth and meets the stringent rejection requirements for microwave radar applications. The filter solution incorporates standard commercial module packaging and is compatible with high-volume, lead-free SMT soldering processes. The product is expected to be fully qualified for high volume manufacturing in the third quarter of calendar 2018.

The AKF-1938 filter features:

  • High frequency operation at 3.8 GHz
  • Wide bandwidth covering 100 MHz
  • Low insertion loss in filter passband
  • High rejection with >40 dB over wide spectrum up to 10 GHz
  • Single-ended 50 Ohm input/output ports
  • Ultra-small form factor packaged module at 2 mm x 2.5 mm x 0.9 mm
  • High operating temperature range from -40 C to +105 C

The Company’s XBAW single-crystal BAW manufacturing process supports a wide range of frequency spectrum up to 7 GHz, covering 2 GHz and 5 GHz WiFi, 4G LTE and emerging 5G cellular and C-V2X applications. In March, the Company announced its first commercial filter product on its proprietary XB1 process, creating the first commercial 5.2 GHz BAW filter designed for use in tri-band WiFi router applications.

The AKF-1938 will support demanding temperature operation and high rejection performance requirements. The product offers low insertion loss in a small form factor enabling compact phased-array radar systems.
