摘要: An RF transceiver achieves a fast switching time between transmit and receive modes by leaving the oscillator (12) on all time. The chain comprises wide pulling voltage controlled crystal that operates at one third frequency followed tripler/filter/amplifier can be quickly switched off. By operating frequency, only harmonic of falls into sensitive band. Further isolation during mode is achieved gating off tripler, out band, electronically detuning filter (16) transmitter's power amplifier (18).
