Abstract: PROBLEM TO BE SOLVED: To provide the transmission and reception switching circuit which has a short transmission/reception switching time and simple constitution and can operate even if the frequency range of a transmit and a receive signal is broad. SOLUTION: At transmission time, the DC current of a transmission ON signal is supplied from a bias supply circuit 19 to a pin diode 17, which enters a short-circuit state, so that the transmit signal from a transmission part 12 is outputted from an antenna 11 through a circulator 14. At reception time, on the other hand, the transmission ON signal is not supplied from the bias supply circuit 19, the pin diode 17 is open, and the receive signal from the antenna 11 is outputted to a reception part 13 which has entered a matching state through the circulator 14 and inputted to the reception part 13.

Abstract: PURPOSE:To improve high frequency characteristic of an InGaAs heterojunction bipolar element by sequentially superposing an InGaAs collector contact layer, an InP collector layer, a collector layer side end with an InGaAs base layer and InP emitter layer, an emitter contact layer on an InP substrate. CONSTITUTION:A main collector zone for determining a collector depleted layer running time of electrons is formed of an InP 3i having high energy posi tion of a satellite lever 9. The collector end of a base layer 4 and a collector contact layer are made of InGaAs, a voltage drop 11 generated at the layer 3i is merely small Eg of the InGaAs except an external collector bias, and the average electric field intensity of the layer 3i is alleviated. Even with the same voltage drop the electric field intensity is deviated to so control distribu tion as not to exceed the height of the lever. As a result, a collector zone in which electrons can run at a high speed without transition to the lever is extended to improve high frequency characteristic.
