DBES105a
Flip-Chip Dual Diode
GaAs Diode
Description
The DBES105a is a dual Schottky diode based
on a low cost 1µm stepper process including a
bump technology. The parasitic inductances are
reduced and result in a very high operating
frequency.
This flip-chip dual diode has been designed for
high performance mixer applications.
Main Features
■ High cut-off frequencies : 3THz
■ High breakdown voltage : < -5V
@ 20µA
■ Good ideality factor : 1.2
■ Low parasitic inductances
■ Low cost technology
■ Dimensions : 0.53 x 0.23 x 0.1mm
