Variable Attenuators
Models 3003, 3006, 3007, 3010, & 3014 dc to 2.5 GHz
Models 3053 & 3054 dc to 6.0 GHz
Manual Step Attenuators 1 Watt
Rugged SMA Connector
Features
oNew Models - Models 3053 & 3054 offer an extended
frequency range to 6 GHz.
oAvailable Express Models: 3003-100
3010-100
3053-100
3054-100
Other models may be available for Express delivery.
oHigh Reliability - Repeatability better than 0.1 dB over
frequency range and life. Weinschel patented detent
mechanism, tested to 1,000,000 operations at +75°C,
operates dependably even down to -40°C.
oProduct Uniformity - High volume fabrication tech-
niques, including injection molding, stamping,
broaching and thick film printing ensure a cost effective
and uniform product.
oLow Frequency Sensitivity - Typically 0.1 to 0.2 dB up
to 2.5 GHz.
oShock Resistant - 100% spring contact system with-
stands mechanical and thermal shock and eliminates
the need for epoxy or solder.
oWide Selection - Wide choice of attenuation ranges
and increments in standard stock models. Single and
dual drum configurations available.
oKnob Included - Knobs for both single and dual drum
models are included with every attenuator. Characters
are screened on the face of the knob insert which is
coated with a clear layer of epoxy for protection.
Special Configurations
Some modifications to the basic configuration of the 3000
Series can be made during manufacturing. Examples of
these special configurations are shafts having special
lengths and ends; clockwise shaft rotation; modified mount-
ing arrangements; and provisions for add-on items such as
concentric potentiometer and ganged switches.
