8 Bit Relay Controlled Programmable Attenuator, 127 dB
Up to 1.5 GHz, 1 dB Steps, +12V, SMA Female

TECHNICAL DATA SHEET PE70A8005

The PE70A8005 is a 7 Bit Relay Programmable Attenuator which operates over the frequency range of DC to 1500 MHz. The
50 ohm design 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 3.2 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 SMA female RF input/output
connectors and DC connector solder terminals. Operational termperature is -20°C to +85°C.
