95 dB Programmable USB Controlled Attenuator, SMA Female
to SMA Female, 1 dB Steps From 200 MHz to 6 GHz

TECHNICAL DATA SHEET PE70A3902

The PE70A3902 is a USB Controlled Programmable Attenuator which operates over the frequency range of 200 MHz to 6000
MHz. The solid state design supports a USB interface and MS .NET 4.0+ framework. The PE70A3902 has an attenuation
range that covers 0 to 95 dB in 1 dB steps. Attenuation steps are 1, 2, 4, 8, 16, 32, and 32 dB bit steps. Insertion loss is 8 dB
maximum with a maximum operating RF input power +20 dBm. Additional typical performance includes +/- 1.0 dB attenuation
accuracy and switching speed of 1 microseconds. The DC supply is +5 Vdc @ 50 mA. The compact and rugged package
design supports SMA female RF input/output connectors, and a USB MINI-B connector for DC and serial controls. A 6 ft USB
A to USB MINI-B cable is included. The PE70A3902 has an operational termperature range of -40°C to +85°C.
