Application Notes for RF Switches
The Model 2578 is a low cost high-performance terminated SP4T switch that operates over the full instantaneous bandwidth of 6 to 18 GHz with ON and OFF times of 250 ns. Design features include an integrated circuit assembly of PIN diodes mounted in a microstrip transmission line.
The Model 2578 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.
