Publication number: 20210218382Abstract: Techniques are disclosed for filtering a radio frequency (RF) signal using an N-path bandstop filter with an extended, spurious-free upper passband. In an embodiment, a bandstop filter includes a bank of three switched capacitors in series with the RF signal path through the filter, in contrast to 4- or 8-capacitor banks or other bandstop filters where N is a power of 2. In this 3-path example configuration, an undesirable spurious bandstop notch at the 3rd and 5th harmonics of the clock frequency are eliminated or substantially reduced, improving performance of the filter in the desired passbands while preserving the notch in the desired stopband at high RF signal frequencies. Another N-path bandstop filter embodiment includes a bridged T-coil circuit, which absorbs a shunt capacitance of the bandstop filter into the bridged T-coil circuit.Type: ApplicationFiled: January 9, 2020Publication date: July 15, 2021Applicant: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Mark D.

Patent number: 11047954Abstract: Techniques are disclosed for determining the presence of pulse jams in an identification friend or foe (IFF) system. In an embodiment, a plurality of jamming pulse rates are determined. Each of the plurality of jamming pulse rates is a count of jamming pulses entering the IFF system during a corresponding integration period. Each of the plurality of jamming pulse rates is a count of jamming pulses associated with non-valid signals entering the IFF system. An average jamming pulse rate is computed based on the plurality of jamming pulse rates.
