The bandwidth characteristic of a microstrip N-pole M-throw switch is improved by providing the spacing, which is between a printed pole conductor and a printed throw conductor thereof and across which is connected a PIN diode to the two conductors, with a predetermined spacing relationship W = 0.215 lambda /3, where lambda is the wavelength at the upper frequency of the bandwidth range of the switch. Further improvement of the bandwidth characteristic is provided by utilizing the inductances of bare wire conductors as chokes or as the inductive component of low pass LC filters that are used in the biasing of the switches.
