PE70A8008

Overview

The PE70A8008 is a TTL-controlled programmable step attenuator manufactured by Pasternack. It operates within a frequency range of 100 MHz to 40 GHz and provides an attenuation range from 0 dB to 31 dB with 1 dB step sizes. The device features a 2.92mm female connector interface and maintains a 50 Ohm impedance system. Designed for high-frequency applications, it supports precise digital control via TTL signals.

Feature Summary

• TTL-controlled digital programming capability
• High-frequency operation up to 40 GHz
• Fine 1 dB resolution step attenuation

Applications

• RF test and measurement instrumentation
• Automated production testing systems
• Telecommunications equipment calibration

Procurement Notes

Verify the specific datasheet version for the PE70A8008 to confirm pinout definitions and TTL voltage levels. Ensure that the host control circuitry matches the required logic standards for reliable operation at frequencies up to 40 GHz. Confirm connector compatibility with existing 2.92mm infrastructure.

Selection Notes

Select this component when precise, digitally controlled attenuation is required in millimeter-wave applications. The 2.92mm interface ensures low VSWR and performance stability at high frequencies. Consider the 1 dB step size for applications requiring fine-grained signal level adjustments compared to coarse fixed attenuators.

Part Context

This part belongs to Pasternack's line of RF variable attenuators. It complements other programmable solutions like the PE70A8003, which operates at lower frequencies (DC to 1000 MHz). The PE70A8008 extends the operational bandwidth significantly, targeting microwave and millimeter-wave spectrum requirements.
