Abstract
In a tubular-core microwave transformer (1) with printed transformer windings (5) for printed microwave circuits arranged on laminated support boards (4), it is provided in accordance with the invention that the tubular core consists of two joined half shells (2, 3) and passes with its legs (8) through one recess (9) each in the support board (4) on which the winding conductor tracks (5) are arranged integrated in the microwave circuit. This achieves both production advantages and electrical advantages: Tubular core (2, 3) and transformer windings (5) can be arranged in or on the support board (4) so that no separate transformer board and no soldered connections between the winding tracks and the associated circuit conductor tracks are needed. This provides for much simpler and inexpensive automatic production. In addition, the support board (4) requires little space. In addition, the connecting and winding conductor tracks (5, 6) have minimum lengths. Together with the gap (14) between the half shells (2, 3), this especially has the effect of significantly reducing the throughput attenuation of the tubular core transformer (1) towards high frequencies (up to 3 GHz) and thus also makes it possible to use it for the planned extension of the first satellite intermediate-frequency range for receiving the ASTRA 1D satellite. <IMAGE>
