Overview

PXI RF Amplifiers

National Instruments PXI RF signal conditioning modules include low-noise/

high-gain ampliﬁers and programmable attenuators. You can use these 3U PXI

modules to optimize the dynamic range of PXI RF vector signal generators and

analyzers. The NI PXI-5690 is a 100 kHz to 3 GHz, two-channel programmable

ampliﬁer and attenuator; the NI PXI-5691 is a 50 MHz to 8 GHz, two-channel

programmable ampliﬁer; and the NI PXI-5695 is a 50 MHz to 8 GHz, two-channel

programmable attenuator.

CH1 IP3 (TOI)

You can use PXI programmable ampliﬁers with both RF signal generators and

RF signal analyzers. When combined with RF vector signal generators, PXI RF

ampliﬁers enable high-power signal generation. For example, the PXI-5691 offers

up to 28 dB of gain and a 1 dB compression point of +21 dBm. Using this module,

you can extend the upper power range of your vector signal generator.

When used with RF vector signal analyzers, the same programmable

ampliﬁers can improve the noise ﬂoor of the measurement system. For example,

with a typical noise ﬁgure of 5 dB at 2.5 GHz, the PXI-5691 programmable

ampliﬁer can be combined with the NI PXI-5663 RF vector signal analyzer to

measure signals down to -163 dBm/Hz.

Note: All values are typical results at either 2.5 or 6.6 GHz.

Table 1. PXI RF Programmable Ampliﬁers Comparison

PXI-5690 RF Programmable

Amplifier/Attenuator

The PXI-5690 is a 100 kHz to 3 GHz, two-channel programmable ampliﬁer and

attenuator with one ﬁxed gain path and one programmable gain/attenuation

path. The combined paths offer up to 37 dB of total signal gain at 2.5 GHz when

signal paths are cascaded.

With PXI programmable attenuators, you can improve the power accuracy of

your RF signal generator in lower power ranges. With an external attenuator,

you generate RF signals in the most accurate range of the signal generator and

attenuate the signal to the desired output power.
