摘要： A stripline split-ring resonator bandpass filter comprises first and second conducting layers and first and second substrates connected to each other between the conducting layers. 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： An oscillator (100) includes a tank circuit (102) coupled to a an active circuit (108). The feedback (104) provides the necessary feedback between the tank and the active circuit necessary for oscillation.

摘要： A substrate 15 has an electrically adjustable trim pad 50 on the bottom side. A circuit pattern 18 resides on the top side, covered by an RF shield 20. The trim pad is located on the bottom side directly below the RF shield, and is electrically connected 52 to the circuit pattern. A number of surface mount connections 30, typically C5 solder bumps, are located on the bottom side, and surround the trim pad. The trim pad is trimmed after the RF shield is attached, thus providing more accurate tuning of the circuit on the top side.
