Abstract: PURPOSE: A loop filter and a frequency synthesizer using the same are provided to obtain stability corresponding to large current change by freely changing a current change ratio which determines a bandwidth of the loop filter. CONSTITUTION: A reference oscillator(100) controls frequency disturbance according to temperature change in a crystal oscillator. A phase-frequency detector(200) transmits an error signal to a current pump(300) by comparing a phase and frequency of a reference signal and an oscillation signal. The current pump provides a specific amount of electric charges to a loop filter(400) according to the error signal or absorbs the electric charges. The loop filter applies a voltage generated by charged/discharged currents to a frequency control input of a voltage controlled oscillator(500). The voltage controlled oscillator outputs an oscillation signal having a frequency corresponding to the voltage of the charged/discharged loop filter. A frequency divider(600) divides the oscillation signal into 1/10 times.

Abstract: An MIC(Microwave Integrated Circuit) complex module is provided to improve operation reliability of an MIC used in a high frequency communication device by connecting a unit MIC module using an FGCPW(Finite Ground Co-Planar Waveguide). An MIC complex module includes a unit MIC module(100), and an FGCPW(140). The MIC complex module is formed by a connection of the unit MIC module using a carrier. A central line and both sides are formed as the FGCPW of three-line structure on the same plane of the unit MIC module, and are connected with three conductive ribbons. A mismatching with a microstrip line of the unit MIC module is minimized by adjusting a width and an interval of each of three lines of the FGCPW. Both sides of a central line of the FGCPW are slantingly connected with both sides of the microstrip line of the unit MIC module having a wider width than the central line at a predetermined position.
