发明名称 ANTENNA SWITCH FOR WIRELESS ANTENNA DIVERSITY TELECOMMUNICATIONS DEVICE WITH TWO ANTENNAS
摘要 In order to minimise switching losses in aerial switches for wireless aerial diversity telecommunications devices with two aerials, e.g. a base station of a DECT wireless telephone, there is an electronic switching component (SE1, ..., SE4) in the form, for example, of a PIN or switching diode, in a first signal path (SW1) from a transmitter (TR) to a first transmission/reception aerial (A1), a second signal path (SW2) from the transmitter (TR) to a second transmission/reception aerial (A2), a third signal path (SW3) from a receiver (RE) to the first transmission/reception aerial (A1) and a fourth signal path (SW4) from the receiver (RE) to the second transmission/reception aerial (A2). The switching components (SE1, ..., SE4) thus form a ring circuit with the signal paths (SW1, ..., SW4).
