IPC: H03F1/32
Filed: 1992-09-29
Abstract: PURPOSE:To provide a nonlinear distortion compensating system which is applied to an amplifier that amplifies the high frequency electric power to be sent to a compact earth station of the satellite communication and can compensate the nonlinear distortions in a wider range. CONSTITUTION:A signal of the intermediate frequency band is inputted and converted into a frequency band slightly lower than the transmission frequency by a mixer 11. Thus a signal having a band narrow enough to the center frequency is obtained and inputted to a distortion compensating circuit for generation of an antiphase distortion. Furthermore the signal inputted to the distortion compensating circuit is converted into a signal having the transmission frequency assigned to an earth station by a mixer 12. Then the converted signal is inputted to a high frequency electric power amplifier for compensation of the nonlinear distortions.

Title: Inter-channel synchronizing device for data transmitter-receiver
Inventor: TATSUMI MASAHIRO
IPC: H04J3/06
Filed: 1991-10-08
Abstract: PURPOSE:To reduce the circuit scale of the inter-channel synchronization device implementing transmission and reception of data through the use of plural channels. CONSTITUTION:When one of synchronizing signal detection circuits 8-13 detects a synchronizing signal, a synchronization monitor section 14 outputs a timing signal generation instruction signal to a 1st timing signal generating section 16 to allow it to generate a synchronizing timing signal. Moreover, the section 14 outputs a switching instruction signal to a timing signal changeover section 18 to apply the generated synchronizing timing signal to a synchronizing signal detection section detecting the synchronizing signal. When other synchronizing signal detection section detects the synchronizing signal, a 2nd timing signal generating section 17 applies a synchronizing timing signal to the synchronizing signal detection section. When the synchronization is established for the two channels respectively, a delay quantity calculation section 15 calculates a delay difference between the tow channels and a delay difference absorbing section 70 eliminates a delay difference between the two channels based on the result of calculation. Every time the synchronizing signal detection section detects the synchronizing signal, the similar operation is repeated, the delay difference between all channels is eliminated finally and the synchronization among all the channels is established.

Title: Optically coupled d-a converter
Inventor: AKAGI TAKATOSHI
IPC: H03M1/74
Filed: 1987-10-19
Abstract: PURPOSE:To facilitate the adjustment of a resistor for the fine adjustment of the weighting of a digital signal, and the setting of a resistance value by weighting the digital signal by changing a distance between a light emitting part and a light receiving part for every bit. CONSTITUTION:The digital signal, inputted from terminals 91-94, passes through resistors 31-34 and emits light after being electricity-light converted by the light emitting parts 21-24. The emitted light passes through transparent molded material 51, and reaches the light receiving part, and is light-electricity converted, and outputs an analog signal from the terminal 81, and D-A conversion is completed. The distance between the light receiving part 11 and the light emitting parts 21-24 is changed previously in conformity with a number of bits, and the signal is weighted. Besides, the resistors 31-34 are adjusted by trimming, etc., so as to make the precision of the D-A conversion high. In this case, since the resistance values inserted in series with the light emitting parts come to be approximately equal to each other, the fine adjustment of the resistor and the setting of the resistance value come to be easy.
