ATEK897N4 is a GaAs MMIC digitally tunable band pass filter offering low 8dB in-band loss and excellent rejection of -40 to -30 dBc from 18 to 26 GHz.
The RF input and outputs are bidirectional and internally matched to 50 ohms for low SWaP transmit and receive applications.
The MMIC filter bank is powered by a single +5V supply drawing 9 mA with an 8-bit GPIO control interface selecting 256 filter states.
Housed in 4×4 mm QFN surface mount package, the monolithic filter bank IC inherently minimizes phase noise degradation caused by mechanical vibration (microphonics).
MMICs and Evaluation Boards are available from stock. Custom package configurations, MMIC die, and module options are available upon request.
