31.75 dB Programmable TTL Controlled Attenuator, SMA Female
to SMA Female, 0.25 dB Steps From 30 MHz to 3 GHz

TECHNICAL DATA SHEET PE70A5004

The PE70A5004 is a 7 Bit Programmable Attenuator which operates over the frequency range of 30 MHz to 3000 MHz. The 50
ohm design supports TTL control logic and has an attenuation range that covers 0 to 31.25 dB in 0.25 dB steps. Attenuation
steps are 0.25, 0.5, 1, 2, 4, 8, and 16 dB. Insertion loss is 2.5 dB maximum with a maximum operating RF input power +20
dBm. Additional typical performance includes +/- 0.5 dB attenuation accuracy and switching speed of 0.7 microseconds. The
DC supply is +5 Vdc @ 50 mA. The compact and rugged package design supports SMA female RF input/output connectors,
and a 10 pin male connector socket for DC and TTL controls. A mating DC cable connector plug assembly (model PE3C4220-
24) is available in stock as an accessory. The PE70A5004 has an operational termperature range of -40°C to +85°C.
