MtronPTI Increases Capacity for Mobile and Airborne Internet

Best-in-class master reference for lab
instruments and satellite communication
MtronPTI, leader in precision frequency control, custom
RF/microwave filters and solid state RF power amplifiers, today
announced the XO5123 Series Ultra-low Phase Noise OCXO to meet the
needs of increasing internet bandwidth. Conrad Jordan, MtronPTI VP
and Timing Business Unit Manager, says, “As digital bandwidth
requirements raise – more people, more video traffic, internet
anywhere – LTE and satellite equipment makers turn to higher
frequencies and more complex modulations. But these shifts mean the
primary frequency reference needs to be quieter. The 10 MHz XO5123
lowers phase noise to -146 dB/Hz at 10 Hz offset and -172 dB/Hz at
high frequencies. Nearly fifty years of crystal science and high
performance oscillator design helps our clients make better LTE lab
measurements and broaden Internet access.”
Digital communication systems, the one that powers your phone or
the one that connects the internet on a commercial flight, use high
frequency radio signals, many channels and complex modulation
schemes. In the face of increasing data transport needs, equipment
makers are moving carrier frequencies up (allowing more channels of
the same bandwidth) and changing modulation to fit more bits into
the same channel. One common modulation scheme involves 256
combinations of phase and amplitude – each choice represents a
small group of digital ‘bits’. To increase the number of bits per
second, radio makers are moving to 1024 or 2048 point schemes.
These points are closer together so measurement errors must go down
to keep the same level of data reliability.
Conrad continues, “The performance limit of an LTE lab network
analyzer or an airborne satellite receiver is limited by the
reference clock noise level. The XO5123 brings very low phase
noise, bringing bench equipment higher accuracy and also adds low
aging to ensure uninterrupted airborne Internet service.”
MtronPTI’s XO5123 Series is shipping now in a small ‘Europack’
36 x 27 mm package with three phase noise level options. Consuming
only 2.5 Watts, aging of <± 0.1 ppm/year and with an Allan
deviation down to 5 x 10-12, the XO5123’s in–house crystal
manufacture and extensive characterization over temperature, shock
and vibration help make measurements a bit more accurate, data
links more reliable and radar pictures a bit sharper.
OCXO – Oven Controlled
Crystal Oscillator: a quartz time and frequency
reference encased in a temperature stabilized oven to guarantee
initial accuracy, minimal shift with ambient temperature changes
and low drift over time. Low Phase Noise OCXOs use selected
specially processed crystals with fewer microscopic faults, special
mechanical mounts and lower noise electronics to minimize output
noise.
