S-Parameters and Impedance Transformation,t and output ports are frequently described by means of the well-known Z or Y parameters. However, for high frequencies, the application of theses parameter is limited since short and open circuits are required for the measurements. Unfortunately, ideal shorts with . =0 and opens with . = ∞ cannot b

Passive Devices and Networks, resistive and reactive parasitics passive devices exhibit losses. We can distinguish between distributed elements such as transmission lines, and lumped elements including inductors, capacitors and resistors ..

Mixers,itters. The corresponding circuits are referred to as down- and up-mixers, respectively. An LO signal provided by a VCO is required for this operation. For capacity reasons and to allow coexistence with other standards, the data has to be transmitted by means of a high RF carrier frequency, whereas

Oscillators, signal as illustrated in Fig. 11.1a. The main function of an oscillator is the generation of the LO signal, which is a periodic output signal at a specific or tuneable frequency. Similar to amplifiers, the efficiency is given by the relation between LO output power and required DC power. In this co

Phase Shifters,cked loops and PA linearisation systems. On the wish list for phase shifters we can find the following performance constraints: 360° phase shift, low loss or even gain, adequate bandwidth, RF power handling and line arity, low power consumption, and small size. In most cases, phase shifters require
