Dynamic Microwave Frequency Division Characteristics of Coplanar Transferred-Electron Devices in a Resistive Circuit (Letters)

It is shown that dynamic microwave frequency division (divide-by-K) can be achieved by employing a transferred-electron device (TED) in a resistive circuit. The absolute bandwidth over which the input signal will be divided by a particular integer K and the maximum output frequency is the device transit time frequency. The percentage bandwidth is 200/(2K - 1) percent. With two-terminal TED's, divide-by-K (K = 2, 3, 4, 5) was demonstrated with substantial bandwidth.
