| Abstract: | An implementation of a solid-state microwave power source with adjustable frequency and power is presented, in which a phaselocked loop (PLL) and a voltage-controlled attenuator (VCA) are used. Then the circuit and test results are given. The results show that the implementation has wide frequency range (400 MHz ~ 500 MHz) and wide power range (-7 dBm ~ 36 dBm). Also the system has high frequency precision (100 kHz) and good power flatness (0.49 dB), which makes the system has wide application value. |
