专利汇可以提供Rf amplifier control system专利检索,专利查询,专利分析的服务。并且Two RF amplifiers may be selectively coupled and decoupled between a single antenna and a single mixer by switching circuits associated with each amplifier. A PIN diode is connected between the antenna and the input of each RF amplifier. A switching arrangement includes a complementary pair of transistors, one connected between a source of DC operating voltage and the amplifier and the other connected between the first transistor and the PIN diode. When the first transistor is biased to conduction by an appropriate control voltage, the associated RF amplifier is activated and DC current flows through both transistors causing the PIN diode to present a low impedance to RF signals from the antenna. When the first transistor is biased to cutoff by an appropriate control voltage, no current flows in the transistors inactivating the RF amplifier and causing the PIN diode to present a high impedance to RF signals from the antenna.,下面是Rf amplifier control system专利的具体信息内容。
