Small Form Factor Omni<br />

Antenna<br />

RFMW, Ltd. announced design and sales<br />

support for small form factor antenna from<br />

Southwest Antennas. The 1001-202 is a<br />

half-wave dipole, omni antenna for 2.1<br />

to 2.5 GHz applications. Measuring only<br />

4.29 inches in height, it offers 2.15 dBi of<br />

peak gain. The antenna features a tough,<br />

black, G10 fiberglass radome and a blackchrome,<br />

TNC(m), non-rotating, RF connector,<br />

making the antenna ideal for lowvisibility<br />

or tactical applications such as<br />

tactical hand-held radios, body-worn radio<br />

systems, unmanned robotics platforms and<br />

other applications where size and weight are<br />

critical. Capable of handling up to 50 W of<br />

RF power, the 1001-202 antenna has a vertical<br />

elevation beamwidth of 77 degrees.<br />

Millimeter-Wave Removable<br />

End Launch Connectors<br />

Pasternack has just released a new line of<br />

high-speed end launch connectors. These<br />

new removable end launch connectors are<br />

perfect for signal integrity measurements,<br />

coplanar waveguide, chip evaluations,<br />

SERDES, substrate characterization, 25 GbE<br />

and test fixture applications.<br />

Pasternack’s new series of high-speed end<br />

launch connectors is comprised of four<br />

models that provide SWR as low as 1.10:1<br />

and a maximum operating frequency of 40 to<br />

110 GHz. Connector options include 1 mm<br />

end launch (110 GHz), 1.85 mm end launch<br />

(67 GHz), 2.92 mm end launch (40 GHz) and<br />

2.4 mm end launch (50 GHz). These highperformance<br />

end launch connectors don’t<br />

require soldering, are re usable and have a<br />

compact profile with a 0.350 inch mounting<br />

width. They feature an outer conductor<br />

made of stainless steel and a gold-plated<br />

beryllium copper center contact. These<br />

highspeed end launch connectors are ideally<br />

suited for high-speed digital and mmWave<br />

system development.<br />

3 GHz Sector Antennas with<br />

Improved Performance<br />

KP Performance Antennas announced that<br />

it has released new high performance,<br />

3 GHz sector antennas to its portfolio for<br />

use in WISP networks. KP’s expanded line<br />

of 3 GHz sector antennas consists of four<br />

new models including the KP-3SX4-65<br />

quad-port 18 dBi sector, the KP-3S3S-65SA<br />

which features two 3 GHz antennas in one<br />

radome, the KP-3DP65S-45 18 dBi Dual<br />

Polarized sector, and the KP-3DP120S-45<br />

3 GHz sector which is specially designed<br />

for LTE applications.<br />

The unique design of these antennas minimizes<br />

interference by utilizing a 65 degree<br />

gain pattern and ±45 degree slant dual polarization<br />

scheme. They are designed to provide<br />

high gain and maximum coverage and<br />

feature improved front-to-back and pattern<br />

roll off that allows for higher spectral efficiency.<br />

These antennas operate in the popular<br />

frequency range of 3.3 to 3.8 GHz and<br />

deliver SWR from 1.5 to 1.7.<br />

Ultra-Low Power<br />

Transceiver for<br />

Bluetooth 5<br />

In the Internet of Things, numerous<br />

tiny sensor nodes are embedded in our<br />

environment. Reducing the power consumption<br />

and enabling operation at low<br />

supply voltage of IoT radio transceivers<br />

is key to enable reliable multi-year battery<br />

life of the billions of IoT devices<br />

in our environment. Furthermore, new<br />

applications are empowered by reducing<br />

power consumption and supply<br />

voltage, such as leave-behind sensors<br />

or wearables.<br />

Imec, together with Renesas, developed<br />

a fully-integrated, highly energy efficient<br />

BT5 transceiver which showcases<br />

the best RX figure-of-merit (FoM) and<br />

the lowest supply voltage among the<br />

state-of-the-art (0.8 V). A low supply<br />

voltage of 0.8 V is beneficial because<br />

it extends battery life by up to 50%,<br />

reduces the complexity of the power<br />

management unit, and allows the use<br />

of a wider range of energy sources such<br />

as energy harvesters.<br />

The transceiver consists of a novel<br />

phase-tracking RX, a digital TX based<br />

on an all-digital PLL (ADPLL) and a<br />

PHY-layer digital baseband. A hybrid<br />

loop filter enhances interference tolerance,<br />

in conjunction with precise frequency<br />

control enabled by the ADPLL.<br />

The receiver fronted achieves a sensitivity<br />

of -95 dBm, while consuming only<br />

2.3 mW (non-duty-cycled) at 0.8 V.<br />

The transceiver chip is implemented in<br />

40 nm CMOS, with a core area of only<br />

0.8 mm 2 , including on-chip matching.<br />
