PIN DIODE
ATTENUATOR, DIGITAL – CELLULAR
3 BIT PLUS “OFF” SWITCH 800–900 MHz
GENERAL INFORMATION
The Model DAS-A11S is a pin diode switched type with series attenua-
tors in a sealed thick film hybrid pin package. The unit includes an extin-
guish switch which provides a total of 65 dB isolation above insertion
loss. The pin diodes provide a robust semiconductor which is often
preferred over GaAs for ESD and sensitivity to voltage spikes. Other
values of attenuation can be provided upon request.
