    Abstract: The present invention relates to a device and method that digitally replicates the analog processing that is normally associated with an instantaneous frequency measurement device. Specifically, the present relates to a digital frequency measurement device comprising: a filter, where the filter receives an input RF signal and transmits an output signal centered around a desired frequency; a limiting amplifier downstream of the filter, where the amplifier receives and amplifies the output signal; a deserializer downstream of the amplifier that continuously samples the output signal from the limiting amplifier; and a digital frequency measurement processor (DFM), where the DIM receives data at a rate of 1/16 of the deserializer sample rate. The DIM transforms the data into multiples stages that are combined in order to produce an estimate of the input signal, where the DIM is implemented through a digital processing device.

    Abstract: What is provided is a receiver-on-a-chip comprising a monolithic integrated circuit that reduces the receiver to a cigarette-pack-sized assembly mountable directly at an antenna element, with a much-increased operational bandwidth and instantaneous bandwidth, increased dynamic range and with a two-order-of-magnitude decrease in size and weight. Moreover, because of the elimination of all of the I/O drivers and attendant circuitry, power consumption is reduced by two-thirds, whereas the mean time before failure is increased to 10,000 hours due to the robustness of the monolithic integrated circuit and use of fiber optics.

    Abstract: The feed for the subject receiver-on-chip is a 30 Mhz to 18 Mhz Rf input (42), which is coupled to an RF pre-select and attenuation or notch filter circuit (44), which is off-chip. The out put of this circuit is amplified by a low noise amplifier LNA (46) and is either switched between a low band pass filter (48) or mixer (50) is used in a single down conversion stage, with the mixer (50) being driven by either 8, 10 or 12 GHz local oscillators on line (52) from a clock and local oscillator (54).
