Title: High-frequency distribution circuit5
Inventor: EPPLE RALF
IPC: H03H7/48
Filed: 1991-07-26
Abstract: In a dual distributor for a VHF/UHF band having in each case one matching and differential transformer (AÜ, DÜ) in each case exhibiting a winding with a tap, the taps being conductively connected to one another, and a decoupling resistor inserted between a connecting point (P), which is optimal for achieving the greatest possible decoupling, of the matching transformer (AÜ) and one of the two outputs (A2), this decoupling resistor is a complex impedance (Z = X + jY), the frequency-dependent resistance (X) of which, forming the required ohmic decoupling resistance, compensates for the loss resistances and the reactance (Y) of which compensates for the main and stray inductances of the two transformers (AÜ, DÜ) over a wide bandwidth. This compensation makes it possible to determine the compensation current flowing through the complex impedance in such a manner that a high coupling loss exists between the two outputs (A1, A2) over a wide bandwidth. The magnitude of this coupling loss, of the bandwidth and of the circuit complexity can be adapted to the individual case by approximating the frequency response of the complex impedance to the nominal frequency response which is essentially mathematically determined. <IMAGE>

Title: Ripple filter circuit
Inventor: OTAWA HISAO
IPC: H03H11/04
Filed: 1985-01-08
Abstract: PURPOSE:To obtain a ripple filter circuit having capability of low power voltage operation with excellent power utilization factor by applying fully feedback to transistors (TRs) of differential constitution so as to stabilize an output voltage. CONSTITUTION:Since an output point OUT of a ripple filter circuit RFC and an input point IN are in the relation of full feedback, its output voltage V0 is equal to a base voltage V1. Since the output voltage V0 is expressed as a difference of voltages dividing the difference of a base-emitter voltage of a transistor Q1 from the power supply voltage VCC by resistors R2 and R3, the voltage is set to a value close to the power supply voltage VCC. Thus, the utilization factor of power is made excellent and the circuit is suitable for the operation at a low voltage power supply. Thus, the ripple filter circuit with excellent power utilization factor and possible for low power supply voltage operation is obtained.
