Pentek has significantly boosted analogue performance in the Model 7141 so that the signal-to-noise ratio and the spurious free dynamic range are improved.

The Model 7141 dual multiband transceiver with FPGA is an enhanced successor to Pentek's popular Model 7140 transceiver, which is widely deployed by many customers for Sigint, software radio and communications applications.

Pentek has significantly boosted analogue performance in the Model 7141 so that the signal-to-noise ratio and the spurious free dynamic range are improved by 10dB when compared with many competing products.

"Because our customers typically use signals covering a wide dynamic range, better signal quality means that small signals previously lost in noise can now be detected".

"This is increasingly important for signal intelligence applications, in particular", says Rodger Hosking, Vice President.

"We accomplished our mission for gaining superior analogue performance by using proprietary design techniques in the analogue front end which was tailored to bring out the best characteristics of the Linear Technology 14bit A/D convertors".

Hosking went on to explain that even though A/D convertor device manufacturers cite attractive specifications, the challenge in realising these specifications depends primarily on the
