8 Bit Relay Controlled Programmable Attenuator, 127 dB
Up to 1,000 MHz, 75 Ohm, 1 dB Steps, +12V, F Female

TECHNICAL DATA SHEET PE70A8004

The PE70A8004 is a 7 Bit Relay Programmable Attenuator which operates over the frequency range of DC to 1000 MHz.
The 75 ohm design has an attenuation range that covers 0 to 127 dB in 1 dB steps. Attenuation steps are 1, 2, 3, 8, 16, 32,
and 64 dB. Insertion loss is 2.5 dB typical with a maximum RF input power 1 Watt average. Additional typical performance
includes +/- 0.5 dB attenuation accuracy and switching speed of 6 milliseconds. The DC supply is +12 Vdc @ 30 mA per relay
(7 relay solder terminals 1 GND solder terminal). The compact and rugged package design supports F female RF input/output
connectors and DC connector solder terminals. Operational termperature is -20°C to +85°C.
