Inventor: YOKOYAMA MASAO
IPC: H04B1/26
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To surely eliminate an image signal by correcting a phase offset and a gain offset generated in an image cancel mixer circuit of an FM stereo receiver. SOLUTION: The image cancel mixer circuit consists of mixers 31, 32, and 33, a 1st phase shifter 34, and a 2nd phase shifter 35. The 1st phase shifter 34 uses two APF 3, 4 whose phase shift is fixed to form 90-degree phase shift, while the 2nd phase shifter 35 uses an APF1 whose phase shift is fixed and an APF2 whose phase shift is adjustable to form a phase shift. The phase of the AFP2 is variable by controlling e.g. a variable capacitor Cv. In the case of correcting the phase offset produced in response to the received frequency, the capacitance of the variable capacitor Cv is controlled in response to a tuning voltage of a channel selection circuit 14. The APF2 shifts the phase depending on the tuning voltage and the mixer 33 eliminates an image signal.

Title: Radar receiver
Inventor: OKAZAKI TAKASHI
IPC: G01S13/44
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To obtain a compact radar receiver where test adjustment is easy and does not require much time by using a capacitance-variable-type capacitor as a circuit component and varying a pass bandwidth within a fixed range. SOLUTION: In a Δch-side intermediate frequency band pass bandwidth variable bandpass filter 36, a capacitance-veriable-type capacitor is used for a capacitor that is inserted in series with a signal path out of its circuit components. By changing the value of the capacitance-variable-type capacitor, the pass bandwidth can be changed. In general, a bandpass filter has characteristics where the amount of attenuation in a passband also changes by L0±ΔL when a pass bandwidth BW0 is changed by BW0±ΔBW.  By using the characteristics and hence varying the capacity of the capacity-variable-type capacitor in a Δch-side intermediate frequency band pass bandwidth variable type bandpass filter 36, the amount of attenuation in the passband of the Δch- side intermediate frequency band pass bandwidth variable type bandpass filter 36 can be changed and hence the relative amplitude balance between Σch and Δch can be adjusted.
