Abstract

This paper describes a lowloss microstrip matching circuit with large bandwidth for connecting an Ortel SL1010 laser diode of nominal impedance of 2 ohms, together with parasitics, to a 50 ohm microstrip line. This technique utilizes a microstrip Chebychev transformer without very wide line widths, to obtain the match at a center frequency of 10.5 Ghz with bandwidth of 9 Ghz, insertion loss of less than 1.5 dB and reflection coefficient of better than -10 dB.
