ATEK1001 is a pre-selector module covering 485 – 8000 MHz frequency band. Pre-selector consists of an SP8T switch followed by 7 fixed frequency sub-octave band pass filters which are followed by another SP8T switch. 8th path is a bypass path which provides user to bypass the filters.
RF Input and Outputs are internally matched to 50 ohms for ease of use.
Pre-selector provides 43 dBm IIP3 which allows users to realize high dynamic range wideband receiver frontends. Sub-octave filterbank architecture improves overall system IIP2.
Pre-selector is housed in custom milled metal enclosure with USB interface which allows simple control and the bias supply.
Custom package and module options are available upon request.
