The EMBRACE RECEIVER is high performance 400- 1600MHz tunable double down conversion unit to 100- 200MHz IF bandwidth. The architecture, LO frequencies and RF, IF amplifiers/ filters have been selected to provide

optimal noise figure, intermodulation products, dynamic range and spurious free performance. An High Selectivity Filter bank is provided to avoid undesired interferences and

increase the dynamic performances.

To select the right filter a control signal TTL/Open collector/dip Switched must be provided.

This receiver includes PAD attenuators and equalization stages to flat the received bandwidth as better as possible.

…tests shown that the GSM signals (1830MHz) can

be received although out of band. In order to reject

them an high selectivity filter after the tile combiner

is suggested.
