Abstract: A duplex unit allowing simultaneous transmission and reception of microwave signals on at least partly overlapping frequency bands, comprising an interference canceller unit and a control unit, the duplex unit being arranged to receive a transmit signal and to output a first part of the transmit signal at an antenna port, the duplex unit further being arranged to receive a receive signal comprising a payload signal at the antenna port, and to output a combination of the receive signal and a filtered transmit signal as an interference suppressed receive signal of the duplex unit.

Abstract: An active antenna (100, 200, 300) comprising a driving loop with first (103) and second (105) sections, each of which extends between end points. Each end point of each section (103, 105) is connected to the closest end point of the other section by a reflection amplifier (101, 106). One reflection amplifier (106) comprises differential ports for signals to/from the active antenna. The active antenna also comprises a passive loop with first (107) and second (108) sections, each of which extends between end points. Each end point of each section (107, 108) is connected to the closest end point of the other section by a reflection amplifier (102, 104). The driving loop and the passive loop extend in parallel to each other and the first and the second section (103, 105; 107, 108) of each of the loops form separated complementary parts of a closed geometrical shape and are built in open waveguide technology.

Abstract: A frequency converter (100, 200, 300, 500, 600) comprising a first mixer (105) arranged to receive a first and a second input signal and to have as its output the sum and the difference of the first and second input signals. The frequency converter (100, 200, 300, 500, 600) also comprises generating means (120) for generating the second input signal and for receiving the output signal of the first mixer (105) and multiplying it by a signal at a frequency which is two times the frequency of the second input signal, thereby generating a product. The frequency converter (100, 200, 300, 500, 600) also comprises adding means (110) for obtaining the sum of this product and the output signal from the first mixer.
