Our MMIC wideband amplifier BGA2714 is designed to
meet the specific needs of LNB designs. It operates from
a conveniently low supply voltage with a low supply current.
Improve the performance of your LNB design with our MMIC wideband amplifier BGA2714.
It delivers best-in-class performance at very low current, is small and needs very few external
components. In short, it’s the ideal 1st stage IF amplifier for LNBs and other low-noise
wideband applications.
A demoboard is available to help further
simplify your design-in process
In addition, it delivers industry-leading performance with a
wide frequency range, high and flat power gain and low noise.
Supplied in a compact, industry-standard SOT363 package,
it simplifies system integration.
MMICs like NXP Semiconductors’ BGA2714 are smart RF
solutions that automatically compensate for temperature and
process variations. They integrate transistors, resistors and
capacitors into a single device, reducing component count
and simplify design. In fact, with the BGA2714 you need just
two coupling capacitors and an RF decoupling capacitor.
