127 dB Programmable TTL Controlled Attenuator, SMA Female
to SMA Female, 1 dB Steps From 700 MHz to 3 GHz

TECHNICAL DATA SHEET PE70A5008

The PE70A5008 is a 7 Bit Programmable Attenuator which operates over the frequency range of 700 MHz to 3000 MHz. The
50 ohm design supports TTL control logic and has an attenuation range that covers 0 to 127 dB in 1 dB steps. Attenuation
steps are 1, 2, 4, 8, 16, 32, and 64 dB. Insertion loss is 6 dB maximum with a maximum RF input power +20 dBm. Additional
typical performance includes +/- 1.0 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 PE70A5008 has an operational termperature range of -40°C to +85°C.
