ATEK672N5 is a GaAs MMIC filter bank with eight sub-octave filters offering fast <200nS tuning speed and excellent rejection of -50dBc from 2 to 18 GHz. Bypass ports are integrated to enable the addition of an external filter, through line, or amplification. 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 18.5 mA with a 4-bit word controlling the selection of the 8 BPFs and bypass path.
Housed in 5×5 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.
