ATEK896BN6 is a GaAs MMIC 1024 state digitally tunable band pass filter with low in band loss and high rejection of -45dBc from 1 to 18 GHz. The filter is controlled by a 3-bit GPIO control interface that selects one of 4 filter sections with each filter high or low pass state selected by an 8-bit GPIO which is combined to yield a desired band pass state. There are 2 bypass paths enabling external filtering, through line, or amplification.
The ATEK896BN6 RF input and outputs are bidirectional and internally matched to 50 ohms for low SWaP transmit and receive applications. A single +5V @ 15mA supply eliminates the need for negative voltage rails.
Housed in a 6×6 mm QFN surface mount package, the monolithic filter bank IC inherently minimizes phase noise degradation caused by mechanical vibration (microphonics). The highly repeatable MMIC manufacturing process also yields minimal part to part variation.
MMICs and Evaluation Boards are available from stock. Custom package configurations, MMIC die, and module options are available upon request.
