Description  
Range (GHz)  
The 3400 Series Programmable Step Attenuators are  
designed for use in automatic test equipment and OEM  
systems operating in the dc to 6 GHz frequency range. This  
series is available in many standard attenuation ranges and  
cell configurations. Custom designed configurations are  
available upon request. Each cell contains a double-pole,  
double-throw relay that provides a zero path or attenu-  
ated path for the RF signal.

MONOTONICITY: dc to 6.0 GHz  
POWER RATING: 1 watt average to 25°C ambient tem-  
perature, derated linearly to 0.25 watt @ 70°C. 50 watts  
peak (5 μsec pulse width; 1% duty cycle)  
Microstrip circuitry and special compensation techniques  
produce flat attenuation versus frequency characteristics.  
The microstrip construction, using thin-film circuit ele-  
ments, ensures product uniformity. To minimize RF  
leakage, the 3400 Series Attenuators are provided with  
gold-plated contact areas and feedthrough filters at each  
control terminal.  
POWER COEFFICIENT: <0.005 dB/dB/watt  
RATED SWITCH LIFE: 5 million cycles operations per cell  
@ 0 dBm  
SWITCHING TIME: 6 msec. maximum at nominal rated  
voltage  
RELEASE TIME: 5 msec maximum  
CYCLING RATE: 5 Hz maximum per relay  
OPERATING VOLTAGE: +12V (+13V maximum; +9V min-  
imum)  
OPERATING CURRENT: 17 mA typical per cell @ +12V  
TEMPERATURE RANGE (Operating): -30°C to +70°C  
TEST DATA: Test data is available at additional cost.
