127 dB Programmable TTL Controlled Attenuator, 75 F Female
to 75 F Female, 1 dB Steps From 450 MHz to 2.15 GHz

TECHNICAL DATA SHEET PE70A5011

The PE70A5011 is a 7 Bit Programmable Attenuator which operates over the frequency range of 451 MHz to 2150 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 4.5 dB maximum with a maximum RF input power up to +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 F type 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 PE70A5011 has an operational termperature range of -40°C to +85°C.
