PURPOSE:To efficiently superimpose signals with less signal attenuation by connecting two grounded emitter transistor (TR) circuits in parallel with a transmission line and connecting the collector to a constant current source respectively. CONSTITUTION:The output of the 2nd signal source 4 is fed to the bases of TRs 9, 10 via capacitors 5, 6. The output of impedances 11, 13 of Z/2 for the impedance matching connected to a power supply 12 turns on the TRs 9, 10. Then TRs 16, 18 connected to a power supply 17 are turned on to conduct a current via resistors 14, 15 and to a transmission line 2.
