Simple Inter-stage Impedance Matching Technique for 5G mm-Wave Systems

Résumé

In this paper, a simple inter-stage impedance matching technique for the communication system is presented. This technique allows to choose the most suitable matching circuit between stages. It is applied to match the output impedance of an LO, with an oscillation frequency of 27.27 GHz and an optimum output power of 5 dBm, to the impedance of the LO input of an up-conversion mixer, with an intermediate frequency IF of 2 GHz and a conversion gain of 10 dB for an IF power of −20 dBm. The circuits are designed in MMIC technology based on the 0.15 µm GaAs pHEMT transistor from the UMS foundry. The integration of these two RF blocks, which are essential in any wireless communication system, allows the optimization of the chip size. The resulting Self-Oscillating Mixer (SOM) circuit has a conversion gain of 6.4 dB for an IF power of −15.4 dB.
