Series F90 Millimeter Wave SPST Switches

Application Notes for RF Switches

SERIES F90

Series F90 switches provide high performance characteristics over the frequency range of 18 to 40 GHz. These
miniature switches measure only .75" x .95" x .42".

The series uses an integrated circuit assembly of up to four PIN diodes mounted in a microstrip transmission line.
The circuit configuration is shown in Fig. 1, below.

Application of a positive current to the bias terminal switches the unit OFF since the diodes are biased to a low
resistance value. With zero or negative voltage at the bias terminal, the diodes are biased to a high resistance and
the unit is switched ON.

SERIES F90

The Series F90 switches are the same as the corresponding Series F90 models except the units are equipped with
integrated drivers as shown in Fig. 2.

The proper current required to switch the unit ON or OFF is provided by the integral driver which is controlled by
an external logic signal. Maximum rise and fall times are less than 10 nsec.
