Low noise LO generators for microwave & mmWave radios
NXP LO generators (integrated VCO/PLL) TFF11xxxHN
Manufactured in NXP’s breakthrough QUBiC4X SiGe:C process technology, these highly integrated,
alignment-free LO generators are low-power and low-spurious solutions that simplify design-in and lower
the total cost of ownership.
These low noise local-oscillator (LO) generators, optimized
for use in many different microwave applications between
7 and 15 GHz, deliver highly accurate performance in a small
footprint. They require no alignment or frequency modification
on the production line, so they simplify manufacturing. High
integration saves board space and makes design-in easier, for
lower overall cost and faster development.
Since these ICs are manufactured in NXP’s industry-leading
QUBiC4X SiGe:C process, they offer better overall RF
performance, are more robust than their GaAs equivalents,
and consume much less power. The process technology also
enables higher integration, for added features. NXP owns the
industrial base for production (wafer fab, test, assembly),
so volume supplies can be assured.
The TFF1003HN is the basis for the entire family of LO
generators. It has VCO coverage of 12.8 to 13.05 GHz and
accepts input signals from 50 to 816 MHz. The divider can be set
for 16, 32, 64, 128, or 256, and the output level is -5 dBm with a
stability of ±2 dB. The family of LO generators is completed by
a range of 18 different devices operating in a center frequency
ranging from 7 to 15 GHz. The RF performance of all these
devices is consistent with the TFF1003HN.
All the LO generators have low power dissipation (330 mW typ),
and all are available in a space-saving 24-pin HVQFN package.
