QR026 High Sensitivity VME Tuner Performance Data

March 2010Ver 1


The QR026 High Sensitivity VME Tuner

Some of the data in subsequent slides refers to the QR019 Receiver. The QR019 is a 3 channel system utilising the same modules as the QR026, which shows equal performance.

The QR026 Tuner integrates a 17 channel pre-selector, a high sensitivity receiver, a control module and a fast switching synthesiser based on Direct Digital Synthesis technology into a compact (19 in x 2U) unit.

The QR026 is suitable for ESM, ELINT and RWR applications across airborne, naval and land based platforms.

The individual VME modules are available for integration into a customer – supplied rack.

RF Input 1dB Compression Point Shall not be less than –10dBm

The plot shows the difference in gain for an RF signal at –40dBm and –10dBm. The result shows less than 1dB of compression at the specified input level. Points

showing < 0dB are due to measurement errors.
