General Notes:
1. The ADS-51V-1000 is a 50 to 1,500 MHz
constant impedance 5-bit digital attenuator
designed to be driven directly from TTL
logic. PIN diode switched attenuator pads
are activated by Advanced Fact
TTL compatible logic drivers, allowing high
speed operation without need of a negative
supply. Careful design of thick film resistive
pads and detailed selection of suitable PIN
diodes provide a wide bandwidth with
minimal phase shift.
2. Screened versions with extended
reliability components are available for
applications requiring the highest reliability.
