As a result the effective dielectric per mittivity in the latter case is higher thus indicating a smaller phase velocity for the even mode Consequently it is necessary to apply phase velocity compensation tech niques to improve coupler directivity which decreases with increasing frequency Figure 42 a shows a typical wiggly line coupler with sawtooth shape of coupled lines which increases the physical lengths of the adja cent edges of the microstrip lines This slows the odd mode wave with little affect on the even mode wave 80 High directivity can also be achieved by using capaci tive compensation Figure 42 b shows the capacitively compensated microstrip directional coupler where two identical lumped capacitors are connected between the coupled lines at their edges Physically these edge capac itors affect the odd mode by equivalent extension of the transmission line electrical lengths with almost no effect on even mode For an ideal lossless operation condition at 12 GHz using standard alumina substrate the compen sated coupled line microstrip directional coupler can improve directivity from 13 25 dB to infinity 81 Capacitive compensation can also be performed by a gap COAXIAL AND WAVEGUIDE SWITCHES RLG has the exact solution you re looking for RLC Electronics manufactures a complete range of RF switches including coaxial in the frequency range from DC to 65 GHz and rectangular or double ridge wavegui

Electronics C 1 J2 If it is necessary to provide the output ports 2 and 3 at one side it is best to use a construction of a microstrip directional coupler with crossed bondwires as shown in Figure 40 b The strip crossover for a stripline direction al coupler can be easily achieved with the three layer sandwich A microstrip 3 dB directional coupler fabricat ed on alumina substrate for idealized zero strip thickness should have the calculated strip spacing of less than 10 um Such a narrow value easily explains the great inter est in the construction of directional couplers with larger spacing The effective solution is to use a tandem connec tion of the two identical directional couplers which alle viates the physical problem of tight coupling since two individual couplers need only 8 34 dB coupling to achieve a 3 dB coupler 75 76 The tandem coupler shown in Figure 40 c has the electrical properties of the individu al coupler when the output ports 1 4 and 2 3 are isolat ed in pairs and the phase difference between the output ports 2 and 3 is of 90 From an analysis of the signal propagation from input port 1 to output ports 2 and 3 of the tandem coupler when the signal from the input port 1 propagates to the output port 2 through the traces 1 2 1 2 and 1 3 4 2 while the signal flowing through the traces 1 2 1 3 and 1 3 4 3 is delivered to the output port 3 the ratio of the scattering parameters
