ATEK1001 is a pre-selector module covering the 485 - 7700 MHz frequency bands. It consists of an SP8T switch followed by seven fixed-frequency sub-octave bandpass filters followed by another SP8T switch. (You can also choose to bypass the filters entirely.) It increases the receiver’s dynamic range by filtering out second-order inter-modulation products (IP2 and IMD2), thereby allowing the receiver to monitor a target signal while rejecting unwanted signals.

ATEK1001’s RF inputs and outputs are internally matched to 50 Ohms for ease of use, and it provides 43 dBm of IIP3, which provides for high-dynamic-range, wide-band receiver front-ends. Sub-octave filter-bank architecture improves overall system IIP2.

ATEK1001 is also available in a custom-milled aluminum enclosure that exposes a USB interface through which it can be controlled.

The Chip

For those looking to build their own front-end solution, we are also offering the MIDAS ATEK950AP6 IC as part of this campaign. It is a sub-octave switchable filterbank covering the 485–7700 MHz range.
