摘要：

A broadband transmit-receive system with excellent isolation, operating in the frequency range 15 to 100 MHz, is described. In transmiting mode the transmitter-probe attenuation for the strong RF pulse does not exceed 1.2 dB, while the transmitter-receiver isolation is better than 42 dB. In receiving mode the transmitter-receiver isolation for the weak nuclear signal is better than 40 dB and the probe-receiver attenuation is equal to or less than 2.6 dB. The system is simple and relatively cheap. © 1993 by Academic Press, Inc.
