| PROBLEM TO BE SOLVED: To provide a wireless electronic communication system receiver which can perform the signal processing in a comparatively wide band of received signals and also can simultaneously process many received signals without increasing the signal distortions. SOLUTION: A receiver 10 includes a special LAN 16, a frequency down converter 18 and an ADC 20 and carries out the wide-band signal processing while keeping its performance. The converter 18 uses a proper mixer 28, a BPA 32, an attenuator 34 and a transformer 36 and adjusts these components for the purpose of attaining the desired frequency down conversion and amplitude control in a desired wide band. A down converter device is selected in response to a specific performance reference of the ADC 20. A special digital channelizer 22 is added to the receiver 10 to receive the digital signals from the ADC 20 and to separate these signals among many channels. COPYRIGHT: (C)2002,JPO | ||||||

| PROBLEM TO BE SOLVED: To improve the coupling of corresponding components by adjusting both or independently one of a relative phase and/or amplitude between signal components and a relative phase and/or amplitude of distortion components. SOLUTION: The signal amplifier system (50) has a first and second amplifier paths (52, 54) for carrying duplicates of signal components. On the first amplifier path, a first amplifier amplifies the signal components to generate distortion components. Duplicates of the amplified signal components and distortion are given to a coupling path (58). On the coupling path, the amplitude and/or phase of the distortion components are/is adjusted without adjusting corresponding to the phase and/or amplitude of the signal components, after canceling the signal components to separate the distortion components. The adjusted distortion components are coupled with a second path where a second amplifier amplifies the signal components and the adjusted distortion components. COPYRIGHT: (C)2001,JPO | ||||||

| A radar performance monitor (RPM) (18) receives a sample of a transmitted signal from a radar system (10) being monitored and couples the signal to a recirculating loop comprising a delay line (70) in order to produce a series of displayed signals which are used to evaluate the operation of a transmitter and the sensitivity and tuning of a receiver in the radar system (10). A multiplexer (54) initially feeds the transmitter sample into the recirculating loop of the RPM (18). If the sample signal is of satisfactory magnitude, a detector (58) actuates the loop's control circuit (60) which causes the multiplexer (54) to close the loop and permit continuous recirculation. In parallel with the path to the detector, the sample signal is coupled to serially connected loop elements including a low-level clipper (66), a loop limiter (68), the SAW delay line (70), an amplifier (72), a voltage variable attenuator (74) and finally a power divider (76) which closes the loop to the multiplexer (54). An output (88) of the power divider (76) is used to generate a signal which is transmitted to the radar system (10) to produce a test pattern on the display of the radar system (10). The radar performance monitor (18) is actuated at the option of a radar operator. | ||||||

| PURPOSE: To provide a non-linear signal transforming device matching the power levels over a wide range. CONSTITUTION: A non-linear processor to be used as a signal limiter or a predistortion equalizer has four ports and a 3dB directional coupler 14. A signal to be distorted is supplied to a 1st port 12 of the coupler and supplied through 2nd and 3rd ports 16 and 28 to a pair of non-linear circuits 399 and 699. The respective non-linear circuits have the source/drain trnasmission line of the FET. The respective non-linear circuits form a non-linear reflection circuit for reflecting energy back to the related port of the coupler while being grounded, namely, short-circuited. The non-linear reflected energy is received by two ports 16 and 28 of the coupler, coupled and appears at a 4th port 12 of the coupler. The input return loss of the processor is improved by mutually matching the non-linear circuits. COPYRIGHT: (C)1993,JPO | ||||||

| PURPOSE: To judge the performance of a radar device by gating a recirculation loop when an intermediate frequency signal exceeds a specific amplitude and displaying a plurality of radar target reflection signals that are coupled to the recirculation loop. CONSTITUTION: A radar device 10 consists of an antenna 12, a modulator- transmitter-receiver(MTR) 14, and a display 16. The display 16 controls the operation of the device 10 and controls a radar performance monitoring device RPM 18. The RPM 18 includes an antenna 20 that is coupled to a frequency converter 22 and the converter 22 is coupled to an RPM loop 80. The RPM 18 is a low-power transponder and the transponder is controlled by a radar operator located at a device 16 of the device 10. Also, the RPM 18 performs the test of the reduction in the power of a radar transmitter and that of the reduction in the sensitivity of the radar receiver for the signal of the radar transmitter frequency. Further, the RPM 18 transmits a series of simulated target signals with a known level when an arrival signal from the device 10 is at a proper power level and frequency.

| PURPOSE: To utilize effectively an amplified output capacity in plural amplifiers by dividing equally an input power from an optional terminal at all times into N and using a power coupler having a function giving an output to said N-set of output terminals. CONSTITUTION: Power couplers 11, 12 and amplifiers 2 1∼2N are inserted between input terminals 1 1∼1N and output terminals 3 1∼3N. The couplers 11, 12 are constituted respectively by hybrid couplers, by which an input power from an optional terminal is divided always into N and an output is given to N-set of output terminals. After the signal from the terminal, e.g., 1 1 is divided equally into N by the coupler 11, the result is amplified respectively by amplifiers 2 1∼2N, the signals are synthesized by the coupler 12 and an output is given to a terminal 3 1 corresponding to the terminal 1 1. Thus, the amplifiers 2 1∼2N give a limit of a maximum output to the total sum of the signal power divided equally into N of the input signal of the terminals 1 1∼1N. Thus, a margin power of a low output channel in the N channels is shared to other channels. COPYRIGHT: (C)1986,JPO&Japio | ||||||

| PURPOSE: To realize a microwave power synthesis circuit consisting of a few number of hybrid circuits and having the same functions as conventional circuits, by inserting a π/2 phase shifter between either one of the 2nd and the 3rd terminals of a microwave branch circuit and a reflection type amplifier. CONSTITUTION: A signal incoming from a terminal 38-1 enters a terminal 39-2, and is returned from reflection type amplifiers 41, 42 through reflection, and because of the presence of a π/2 phase shifter 45, the signal is returned to the terminal 39-2. Further, the signal also enters an inlet 40-1 with π/2 phase shift and is returned to the inlet 40-1 with the presence of a π/2 phase shifter 46 and reflection amplifiers 43, 44. As a result, the synthesized signal is outputted at a terminal 38-2. In constituting the power synthesis circuit for 2 n-sets of amplifiers, convenional systems require 3.2 n-1-2 sets of amplifiers, while this system requires only 2 n-1 sets of amplifiers.
