THE THREE UNITS
IN THIS SERIES
ARE EQUIPPED With
INTEGRATED DRIVERS

SERIES F892

Series F892 high speed switches with integrated drivers are low-cost units that have been engineered to meet the need of microwave system designers for fast switching devices in small packages.

2 To 18 GHz Frequency Range

Frequency coverage from 2 to 18 GHz is provided by the three models in the Series: Model F8922 (2-4 GHz), Model F8924 (4-8 GHz) and Model F8928 (8-18 GHz). Each model is capable of extended bandwidth operation, typically 3:1, with only moderate degradation in performance at the band edges, as shown in the specifications below.

Fast Switching Shunt Design

All models are optimally designed, with respect to their size, for low VSWR and Insertion loss. As shown in the schematic below, a pure shunt design is used for the most practical realization of fast switching action. Although the use of a pure shunt mode imposes certain bandwidth limitations, frequency coverage in excess of octave bands has been maintained. Series F892 Octave Band Switch RF schematic diagram
The proper currents required to switch ports ON or OFF are provided by the integrated drivers which are controlled by external logic signals.
