Abstract: A suspended substrate coupler (50) for operation at frequencies of 26 GHz or higher operated in a forward coupling mode. Coupling tends to improve with increased frequency and coupling as tight as 2dB is provided for frequencies of 40 to 60 GHz. The first (561, 562) and second (581, 582) coupled lines are suspended striplines provided on both surfaces (70A, 70B) of a dielectric (70) supported between two parallel ground planes (521, 522). The spacing (S) between the coupled striplines is approximately an order of magnitude greater than the spacing between the coupled lines of a conventional contra-directional coupler, and the length (L) of the coupled sections of the striplines is not required to be a multiple of a quarter wavelength.

Abstract: A handheld vector network analyzer (VNA) (300) providing a wide bandwidth test signal Fo utilizing a narrowband test signal synthesizer (700) which provides the test signal through a frequency divider (710) or harmonic generator (802). With a 550-1100 MHz narrowband test signal synthesizer, a test signal Fo can range from 25 MHz to 3.3 GHz. To make a tracking synthesizer (720) operate more independent of the test signal synthesizer (700), a LO signal is produced using the tracking synthesizer (720) with its phase detector (726) input connected through a frequency divider (800) to the output of the test signal synthesizer. Synchronous detectors are further included which provide incident and reflected IF signals to take advantage of the maximum range of an A/D converter. To better enable operation in the presence of external signals, feedback is provided from the synchronous detectors to sweep the frequency of a reference oscillator (940).

Abstract: A simulator for testing the performance accuracy or calibrating a collision avoidance radar system. The simulator includes circuitry for receiving a signal from the collision avoidance radar system and for generating a signal tracking the frequency of the radar system. Circuitry is further included in the simulator utilizing the tracking signal to generate a signal offset in frequency from the collision avoidance radar system output signal and to transmit the offset signal to the collision avoidance radar. The offset is controlled so that the collision avoidance radar should indicate an object is located a distance (D) away. Circuitry is further included in the simulator so that the offset has a first value when the radar system output is increasing in frequency and a second value when the radar system output is decreasing in frequency. The first and second offset values are controlled so that the radar system should indicate an object is moving at a rate (dD/dt) upon receiving the offset signal. The simulator further indicates the frequency range and amplitude of the radar system output as determined from the tracking signal.

Abstract: A fault-location operating system for use with transmission networks using repeaters with loopback capabilities. A plurality of bidirectional transmission links Li, for i = 1 through N, are used for transmission of data between the terminals (103, 104). A test control unit (107) is connected at the first terminal (103) to the first end of the first transmission link L1, and controls transmission of control signals across the first transmission link L1. A plurality of repeaters Ri, for i = 1 through N-1, are used for interconnecting the plurality of bidirectional links. In addition, a loopback circuit (Fig. 10B, 10C) is included in each repeater that is responsive to the control signals on the one transmission link Li for looping back data transmitted from the one transmission link Li for transmission back on the one transmission link Li.
