===== Wirebonds =====
Based on the webpage [[https://www.microwaves101.com/encyclopedias/wirebond-impedance-and-attenuation|Microwaves101]] plus some own research.

<WRAP left round box 100%>
**Rule of thumbs:**
  * one-mil wire bonds ($25~\mathrm{\mu m}$ diameter), length in millimeters is nearly equal to inductance in nano-henries.
  * one-mil ($25~\mathrm{\mu m}$) wire that is 1mm (40 mils) long will present about 50 ohms of reactance at 10 GHz.

One can accept on the order of 50 Ohms reactants. TODO: Add a simulation of the reflection from such a four-port.
