A first stripline ring resonator is located on the top side of the second nonconducting substrate and is coupled to the input port of the BPF. The first stripline ring resonator has a gap located therein. A second stripline ring resonator is also located on the top side of the second nonconducting substrate between the first stripline ring resonator and the output port of the BPF. The second stripline ring resonator has a gap located therein. The first substrate has at least two slots therein to allow lumped capacitors to be placed in the gaps in the first and second ring resonators.

    摘要: An oscillator (200) with improved sideband noise is disclosed. This improvement is accomplished without affecting the Q or the output power of the oscillator (200). The improvement is realized by increasing the rate of change of reactance over frequency. The increase in the rate of change is realized by placing two transmission lines (208, 210) in close proximity of each other. This increase assures oscillation while minimizing the sideband noise, and providing maximum bandwidth.

    摘要: A frequency synthesizer circuit, having first and second modes of operation, comprises a voltage-controlled oscillator (VCO) (64), a low-pass filter (74), a phase-locked loop (PLL) (67), an analog-to-digital converter (50), a digital-to-analog converter (56), a controller (48), and a VCO input switch. During the first mode, the VCO input switch couples the control input of the VCO to a control signal produced by the PLL, and the analog-to-digital converter measures the control signal and provides it to the controller which stores the control voltage measured by the analog-to-digital converter. During the second mode, the VCO input switch couples the control input of the VCO to the digital-to-analog converter which applies the stored control to the control input of the VCO.
