Attenuation range of up to 60 dB
Up to octave bandwidths
Analog control voltage
Lowest insertion loss
Analog PIN attenuators optimized for the communication bands are available from MITEQ. Attenuation ranges up
to 60 dB can be obtained with our standard products. We also offer as custom products 5-bit digital attenuators with
an LSB of 1 dB and maximum attenuation of 30 dB. This design is ideal in IF applications up to 3 GHz. Custom
PIN attenuators that cover octave bands are available. We also offer MESFET-based attenuators covering 0.2 to
40 GHz in multioctave bands. These products offer very broad bandwidths and fast response time.

* VSWR is guaranteed over full attenuation range.
** Amplitude response: ±0.2 dB p-p over any 40 MHz window, 1 dB p-p over full band from 0–30 dB attenuation.
*** Insertion loss occurs at 0 V control.
Custom models featuring broader bandwidths, and/or optimized specifications are also available. Consult factory for options.

ORDERING INFORMATION
MPAT- Model number - Desired attenuation (10–60 dB) - Desired control voltage (0–20 V)
Example: To specify a 10.7–12.75 GHz, 40 dB attenuator with a control voltage of 15 volts, the following ordering
information would be used: MPAT-107117-40-15.
ORDERING INFORMATION FOR RF CONNECTORS
Unless otherwise specified all units will be shipped with field replaceable SMA female connectors on the input and
outputs. If male connectors are desired on any ports, please specify on the purchase order.
