摘要： A channelised bearing processor comprises a channelised receiver consisting of a plurality of i.f. receivers (34 to 42) covering contiguous parts of a predetermined frequency range. Each of the receivers (34 to 42) is connected to a respective, continuously energised local oscillator (35 to 43). A plurality of direction finding antennas (10 to 15) are coupled to respective receiving channels for producing an amplitude signal. Each receiving channel includes a tunable i.f. receiver (24A to 24F) having an input (26A to 26F) for a local oscillator signal. A local oscillator selector (50) is responsive to an output from one of the channelised receivers (34 to 42) to connect the local oscillator (35 to 43) connected to that one of the channelised receivers (34 to 42) to the local oscillator signal inputs (26A to 26F) of the tunable i.f. receivers (24A to 24F) in the receiving channels.

摘要： An image reject mixer arrangement 1 comprises a transconductor 2, first and second mixer cores 3 and 4, first and second phase shifters 5 and 6 and a summer or combiner 7. The mixer arrangement 1 receives a single-ended RF voltage signal on a terminal 8, a differential local oscillator signal on I-LO terminals indicated at 9 and a 90° phase shifted differential local oscillator signal on Q-LO terminals 10, and provides differential IF output signals on output terminals 11. From the output of the transconductor 2 to the output of the combiner 7, the image reject mixer arrangement 1 carries signals in what can be described as a “current mode”, i.e. it is the current, not the voltage, which conveys the desired signal. In this current mode, it is advantageous to provide each active circuit block with a high output impedance and a low input impedance wherever possible. This is achieved by the cascode connection of the transistors of the transconductor 2 with the transistors of the mixer cores 3 and 4; and the cascode connection of the transistors of the of the mixer cores 3 and 4 with the transistors of the combiner 7. This is advantageous in providing improved noise performance, linearity and current consumption in comparison with cascade connected mixer arrangement circuit blocks.
