摘要
An active UHF amplifier includes a transistor having a base for receiving signals, a grounded emitter, and a collector for outputting signals, a first inductor having a first end for coupling to a voltage source, the inductance of the first inductor being between 10-100 nano-Henries, a first capacitor having a first end coupled to the first end of the first inductor, a second inductor having a second end coupled to the base of the transistor, the inductance of the second inductor being between 1-100 nano-Henries, a second capacitor having a first end coupled to a first end of the second inductor, the capacitances of the first and the second capacitor being between 10 pico-Farads and 100 nano-Farads, a first resistor, and a second resistor having a resistance divided by the resistance of the first resistor and multiplied by a voltage of the voltage source being between 0.5-0.8 volts.
