ABSTRACT:
A transmit/receive circuit employing passive elements. A transmit/receive circuit according to an embodiment of the present invention includes a transformer having a primary winding coupled to an input stage and an output stage. A transducer is coupled to the secondary winding of the transformer. A diode limiter is coupled to the input stage and a diode bridge is coupled to a node at the output stage. The input and output stages are alternatingly grounded. An output switch including an inverse parallel circuit of two diodes having opposite polarities may be connected at the output stage between a transmitter and the transformer. Alternatively, a complementary common emitter amplifier may be provided at the output stage. The circuit thus electrically couples the transducer element to the receiver during reception and electrically decouples both the transducer and the transmitter from the receiver during transmission. The circuit further electrically couples the transducer to the transmitter during transmission and electrically decouples both the transducer element and the receiver from the transmitter during reception.
