Model F940H is a high‑performance broadband transfer switch that operates over the full instantaneous bandwidth of 0.5 to 18 GHz with ON and OFF times of 30 nsec. Design features include an integrated circuit assembly of PIN diodes mounted in a microstrip transmission line as well as a resistive bias line that contributes to the broadband low‑loss performance. The circuit configuration of the Model F940H is shown below.

The Model F940H is equipped with an integrated driver that is powered by +5 and –12 volt supplies. The proper currents required to switch the ports ON or OFF are provided by the driver, which is controlled by external logic signals.
