8 Bit Relay Controlled Programmable Attenuator, 63.75 dB
Up to 2 GHz, 0.25 dB Steps, +12V, SMA Female

TECHNICAL DATA SHEET PE70A8002

The PE70A8002 is a 8 Bit Relay Programmable Attenuator which operates over the frequency range of DC to 2000 MHz.
The 50 ohm design has an attenuation range that covers 0 to 63.75 dB in 0.25 dB steps. Attenuation steps are 0.25, 0.5, 1,
2, 4, 8, 16, and 32 dB. Insertion loss is 3.5 dB maximum with a maximum RF input power 0.5 Watt average. Additional typical
performance includes +/- 0.3 dB attenuation accuracy and switching speed of 6 milliseconds. The DC supply is +12 Vdc @
30 mA per relay (8 relay solder terminals, 1 GND solder terminal). The compact and rugged package design supports SMA
female RF input/output connectors and DC connector solder terminals. Operational termperature is -20°C to +85°C.
