31.5 dB With 6 Bit Programmable TTL Controlled Attenuator,
SMA Female to SMA Female, 0.5 dB Steps Up to 13 GHz

TECHNICAL DATA SHEET PE70A4000

The PE70A4000 is a 6-Bit Digital Attenuator that has 31.5 dB of total attenuation with bit values of 0.5 (LSB), 1, 2, 4, 8, and
16 dB across a wide frequency range from DC to 13 GHz. The design is based on GaAs IC technology that offers exceptional
performance characteristics that include 5.5 dB typical insertion loss at 13 GHz, +38 dB input IP3, and fast switching speed of
45 nsec. The design also features excellent Attenuation Accuracy with +/- 0.3 dB typical bit error and single control lines per
bit that are CMOS compatible. The drop-in package is hermetically sealed and supports Field Replaceable SMA connectors.
And for added confidence, this rugged package assembly is deisgned to meet MIL-STD-883 test conditions for Hermeticity
and Temperature Cycle.
