5. Pitch-and-roll stages
OES' expanded series of
Pitch-and-Roll Stages measure
pitch-and-roll, do micromachining,
align mirrors for scanning electron
microscopes, rotate objects to
precise positions, measure angles
of objects or move an object to
a precise angular position along
an arc, examine cutting edges of
medical instruments, estimate
measurements of radiation
patterns of LEDs, hyperspectral
bidirectional reflectance, or
provide orthogonal rotation. The
stages meet the requirements of
applications such as: Angle range
- 20O (± 10 O), 30 O (± 15 O), and
90 O (± 45 O), height of rotation,
size (footprint), and load capacity.

6. RF and microwave
signal generator
expands frequencies
The analog microwave signal
generator R&S SMA100B now
provides microwave signals up
to 67 GHz with industry-leading
RF performance. In overrange
operation, it even provides
signals up to 72 GHz. The R&S
SMA100B generates signals with
lowest single sideband phase
noise and highest output power
with extremely low harmonics
at the same time. With the new
frequency options, the R&S
SMA100B now covers frequency
ranges of up to 31.8 GHz, 40 GHz,
50 GHz and 67 GHz. Thanks to its
ultra low phase noise option, the
R&S SMA100B can output the
purest RF signals with a single
sideband phase noise of -120
dBc/Hz (40 GHz, 20 kHz offset;
measured).

7. 550 to 650W modular 8. Multichannel,
power supplies
mixed-signal RF
converter platform
The TDK-Lambda brand QM4
modular power supplies, rated
at 550 to 650W, further extend
the QM series, which can
provide up to 1500W output
power. The QM4 models are
available with up to 10 outputs,
have full MoPPs, isolation, and
low acoustic noise. The power
supplies are suitable for use in
medical, test and measurement,
communications and broadcast
equipment. Accepting a wide
range 90 to 264Vac, 47-63Hz
input (440Hz with reduced PFC),
the QM4 can deliver 550W at low
line and 650W with a high line
180-264Vac input and will operate
in ambient temperatures of -20 to
+70°C (-40°C start-up).

Analog Devices introduces a
mixed-signal front-end (MxFE)
RF data converter platform that
combines high-performance
analog and digital signal
processing for a range of
wireless equipment, such as
4G LTE and 5G millimeter-wave
(mmWave) radios. ADI's new
AD9081/2 MxFE platform
allows manufacturers to install
multiband radios in the same
footprint as single-band radios,
which can triple call capacity
available in today's 4G LTE base
stations. With a 1.2 GHz channel
bandwidth, the platform also
enables wireless carriers that are
adding more antennas to their cell
towers to meet the radio density
and data-rate requirements of
mmWave 5G.
