63 dB Programmable TTL Controlled Attenuator,
75 F Female to 75 F Female, 1 dB Steps Rated
to 30 Watts From 5 MHz to 2.15 GHz

TECHNICAL DATA SHEET PE70A5012

The PE70A5012 is a 6 Bit Programmable Attenuator which operates over the frequency range of 5 MHz to 2150 MHz. The 75
ohm design supports TTL control logic and has an attenuation range that covers 0 to 63 dB in 1 dB steps. Attenuation steps are
1, 2, 4, 8, 16, and 32 dB. Insertion loss is 5.25 dB maximum with a maximum RF input power up to +10 dBm. Additional typical
performance includes +/- 0.5 dB attenuation accuracy typ and switching speed of 5 microseconds. The DC supply is +5 Vdc
@ 220 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 PE70A5012 has an operational termperature range of 0°C to +70°C.
