0.5-11.5 GHz Divide by 4 Static Prescaler
GaAs Monolithic Microwave IC
Description
The CND2050 is a low power consumption
and very high speed divider by 4
manufactured with a 0.6m GaAs self
aligned implanted MESFET process.
The design is full differential input/output
that allows direct drive into 50
load.
The CND2050 is available in SOIC8
package form .
Main Features
