NOTES:
1. Tolerance on 3 place decimals
±
.010(.25) except as noted.
2. Dimensions in inches over millimeters.
3. Lead dimensions apply only at body.
4. All unmarked terminals are ground.
General Notes:
1. The ADS-41V-1000 is constant impedance, 4-bit digital attenuator covering 50 to 1500 MHz and driven directly by TTL logic. PIN diode switched attenuator pads are
activated by Advanced Fact
C-MOS, TTL compatible logic drivers, allowing high speed operation without need of a negative supply.
2. Careful design of thick film resistive pads and detailed selection of suitable PIN diodes provide a wide bandwidth with minimal phase shift.
