At, avoid the machine transmitting signal be transferred to receiver.The adjustable filter 302 of frequency be used to eliminate harmonic wave in transmission path,
Burr and noise, at the same eliminate on RX path with outer energy.The adjustable amplifier 301 of frequency is specifically, for example, that low noise is put
Big device, for being amplified before frequency reducing is converted to the downlink radio-frequency signal received, it is therefore an objective to using this amplifier than secondary
The obvious superior low-noise characteristic of grade device, increases the intensity of downlink radio-frequency signal.Further, receiving branch can also include frequency
The adjustable low noise input filter of rate, Conduction Interference and radiation interference for inhibiting frequency converter to generate, is provided simultaneously with common mode
With differential mode rejection ability.
Transmitting branch may include: the adjustable amplifier 306 of frequency, and the adjustable filter 305 of frequency, frequency are adjustable double
Work device 303 and the adjustable power amplifier 304 of frequency.Wherein, upstream radio-frequency signal power very little caused by modulating oscillator,
It needs by a series of amplification, the amplification of the adjustable amplifier 306 of frequency, final power amplifying stage obtain enough radio frequencies
It after power, is radiate just can be fed on antenna 40, in order to obtain sufficiently large radio frequency power output, it is necessary to use radio frequency
