Features

Wide Variable Attenuation Range - Variable attenua-

tion range of 60 dB for Model 940-60 and 114 dB for

Model 940-114, with minimum insertion loss at 6 dB.

Approximately Linear Calibrated Dial - Direct reading

dial individually calibrated in approximately linear 1 dB

increments from 6 dB to full scale.

Model 940-114: ~ 270°

CYCLE LIFE: A cycle consists of a rotation from minimum

to maximum and back to minimum

ments of MIL-A-24215.

Long Life - These variable attenuators offer a cycle life

of up to 10,000 cycles. Optional models are also avail-

able to extend the life to 50,000 cycles.

PHASE SHIFT WITH CHANGE IN ATTENUATION:

1° per dB x f(GHz) maximum

POWER RATING: 5 watts average to 40°C ambient tem-

perature, derated linearly to 0 watts @ 85°C. 500 watts

peak (5 μsec pulse width; 0.5% duty cycle).
