Hi welcome to Nuvotronics at IMS 2016. We're here to present you a new
E-band radio high power and so Nuvotronics is in North Carolina we are
80 people and we are mainly doing millimeter-wave hardware RF going from
passive components all the way to subsystem. Today what I'm going to
present you is a new E-band radio the radio use Polystrata AirCoax. The Air
Coax allows you to have very low loss high isolation structure, is being tested
for very high shock and vibration as well as microphonic and can handle very
harsh environmental. The radio that we're presenting today is a E-band radio that
includes an analog predistorter with include a VGA and then the phase
Compensation. We have a synthesizer that is inside the radio that generate twelve
Gigahertz(GHz)from a VCO and a PLL. The LO is then generated and we can create a 72
Gigahertz(GHz) E-band radio that has high power. So the radio consists of four PA
that are transmitting about 5.2 gigabit per second(Gbps)using a 64QAM radio. In
order to test the radio we are using Keysight equipment. So we start by
generating the I and Q with the arbitrary waveform generator, the M8190A. The
power is then transmitted to a 64QAM with 800MHz of bandwidth and it's
transmitted
to the antenna. The feed horn at the other side then goes to the Keysight
M1971 smart mixer and it's down converted to go to either the N9030A the PXA
signal analyzer that allows us to measure the different frequencies, the LO
as well as the sidebands and then we can go to the auxiliary which is your
high-definition oscilloscope and we can measure then the constellation of the
Signal. So I’ll show you the radio Operating. OK, so here is live E-band radio
very compact high-power E-band radio so the E-band radio is located here on this
platform we are entering with I and Q and then a 10MHz clock
comes in and just one cable for the power. so we are transmitting 64QAM
over 800MHz bandwidth. You can see here the constellation of the
signal and we are demodulating that with the oscilloscope and looking at
the performance. You can see about 3% EVM that is the performance of the radio.
So the radio, the Nuvotronics radio, allows you to have high power very
compact form factor and if you want more information please come on our website
