RF & Wireless
+/-5 ppb frequency stability in a 24 hour
period at constant temperature. Operating
temperature range is -40 to 85 °C, making
the device suitable for 4G and 5G implementations.
Frequencies are available between
8 and 50 MHz with standard frequencies
of 10, 12.8, 20, 16.384, 19.2, 20, and
22.1184 MHz. For example, the MX-5030-
EAE-3080-10M0000000 provides a 10 MHz
output frequency with +/-30 ppb stability
with a HCMOS output operating on a 3.3
V supply. Package size is 9.5 x 14.4 mm.

GaN PA Supports Ka-Band
Electronic Warfare
RFMW announced design and sales support
for a high frequency power amplifier from
Qorvo. The Qorvo TGA2222 offers 10 W
of saturated power with large signal gain of
16 dB. Ideal for Ka-Band radar and electronic
warfare designs operating within 32
to 38 GHz, the TGA2222 also finds uses in
satellite communication systems. A balanced
architecture minimizes performance sensitivity
to load variation and RF ports are DC
coupled to ground for optimum ESD performance.
With the advantages of GaN on
SiC fabrication, the device draws 640 mA
from a 26 V supply and is offered as a 3.4
x 2.6 mm DIE.

Flat Panel TVWS Antenna
KP Performance Antennas has expanded its
line of TV White Space (TVWS) antennas
that are ideal for use with Redline Communications’
2x2 MIMO radios used in WISP
network applications.
KP’s TVWS antenna lineup now includes
the KP-TWDPFP9 flat panel TVWS antenna
that provides high gain of 9 dBi and very
good front to back ratio all in a small form
factor, UV resistant ABS plastic radome
with an aluminum backplate. Additional
features include H/V dual polarization and
a pole mounting bracket with up or down
tilt adjustment. This TVWS Flat Panel
Antenna operates in the 470 to 698 MHz
range and is compatible with any connectorized
TVWS radio, including the Redline
Communication’s RDL3000 Ellipse series
with a direct mount option.

2-Channel Attenuator
Assembly Covering 100 MHz
to 18 GHz
The JFW model 50BA-043-63 SMA is a
2-channel attenuator assembly that covers
100 MHz to 18 GHz. Each RF channel consists
of a solid-state programmable attenuator
with attenuation ranging 0 to 63 dB
in 0.5 dB increments. The attenuators can
be controlled individually or as a group by
Ethernet, RS-232 (GUI provided), or manually
via momentary toggle switches on the
front panel.

Super Simple Cellular IoT Prototyping
Nordic Semiconductor announced that
Dutch IoT R&D startup, Actinius, is now
shipping a plug&play development board
and firmware with Adafruit FeatherWing
compatibility that is so fully engineered
that Actinius claims there isn’t a simpler
or easier path into cellular IoT prototyping
available anywhere in the world right now.
By early next year this simplicity will be
further enhanced with full cloud connectivity
that Actinius says will be equally
fully engineered.
The tiny (50.8 x 22.8 mm) Actinius Icarus
IoT Board retails for around $100 and
employs a Nordic Semiconductor nRF9160
System-in-Package (SiP) to offer low
power GPS and multi-mode LTE-M and
NB-IoT cellular IoT operation globally; a
64 MHz Arm Cortex-M33 processor supported
by 1 MB of Flash and 256 KB of
RAM memory; support for both Nano SIM
and embedded SIM (eSIM) technology;
state-of-the-art ARM Trustzone and ARM
Cryptocell 310 security; and an over-theair-update
(OTAU) platform developed by
Actinius that is said to support “always
secure and up-to-date firmware”. In addition,
a vast range of sensor and peripheral
interfaces includes an Adafruit Feather-
Wing compatible form factor and pinout
layout to give users easy access to a vast
range of add-on development options.
The Icarus IoT Board also ships with fullydeveloped
firmware that users can either
customize themselves or employ Actinius
to customize via what Actinius describes
as “firmware as a service”. It also includes
a solar panel connection which could
enable solar energy to supply most of the
power (depending on application and duty
cycle) and thereby allow the use of very
small batteries.
