Covering a frequency range of 1.8 to 2.2 GHz, the PE46120 integrates a 90-degree hybrid splitter, 5-bit digital phase shifters and a 4-bit digital step attenuator
along with a low-voltage, CMOS serial digital interface.
For example, to characterize receiver sensitivity, test engineers may insert a step attenuator
between the transmitter and the receiver, recording the bit error rate at each signal power level.
With an integrated step attenuator
and featuring fully-matched RF ports, it supports faster product development cycles and requires less PC board space than other, more discrete solutions.
A B-29 was placed at my disposal, and I fitted a step attenuator
to the APS-23 bombing radar.
The 8312 attenuator is comprised of a highly adaptable platform that allows the configuration of the step attenuator
to be matched to the user's requirements using either the front panel controls or a remote controller.
ADI also offers integration around our gain block amplifiers with the inclusion of a digital step attenuator
, DSA, in the ADL5240 VGA and the inclusion of those two functions with a 0.25-W driver amplifier in the ADL5243 VGA.
The RF level of a signal generator is determined by the power amplifier and switching in the step attenuator
, and both have an effect on phase.
A step attenuator
, such as AA101-80 from Alpha Industries, can be inserted inside the repeater to adjust the gain of the repeater when necessary.
The SMB B112 option equips the R&S SMB100A with a wear-free electronic step attenuator
. An electronic step attenuator
is suitable when the generator's level settings must be changed frequently.
The dynamic range is maximized with an optional 2-dB mechanical step attenuator
over the full frequency range and, for manufacturing, an optional 1-dB electronic attenuator to 3.6 GHz.
