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

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.

Standard Unit: One terminal is connected to case ground
and the remaining terminals are provided for activation of
individual cells. Attenuation is fail-safe to "0" setting in the
absence of a control voltage. Application of a voltage (+) to
a particular cell causes it to switch to the attenuate position.

MODELS WITH BUILT-IN DRIVERS: Most 3400s are avail-
able with an intelligent interface\driver cards. These are
designed to interface with our 8210A Series Controllers
which greatly simplifies computer control applications. Refer
to Model 3406T and 3408T data sheet for more information.
Units with TTL Option: Units with this options are supplied
with a very low profile connectorized TTL interface board
mounted directly to the control terminals. This TTL interface
option is available with a 10 pin ribbon cable connector and
is supplied with a mating connector. Refer to Physical
Dimensions for mating connector pin/wiring details. Two
wires are specified for supply voltage and ground. The
remaining wires will accept TTL control signals to activate or
de-activate a particular attenuation cell. A TTL high will
energize a cell to the high attenuation state, whereas a TTL
low will maintain a cell in its zero attenuation state.
To order 3400 Series Attenuators with this option add -1 to
basic model number for ribbon cable connector. Example:
Model 3406-63 with a TTL interface would be 3406-63-1.
