General Description
The HMC1044LP3E is a programmable bandwidth
LPF (Low Pass Filter) targeted at all applications that
use quadrature modulators and/or demodulators. The
HMC1044LP3E filters out LO harmonics and ensures
little or no LO contribution to modulator sideband
rejection or demodulator image rejection performance.
Although targeted at LO filtering applications, the
HMC1044LP3E can be used to filter all RF harmonics
such as the ones generated by amplifiers.
The HMC1044LP3E offers a choice of 16
programmable bands, optimized for high and low
cellular bands ranging from 1 to 3 GHz, making the
HMC1044LP3E a truly wideband part compatible with
wideband PLLs with Integrated VCOs and wideband
quadrature modulators and demodulators. It enables
wideband multi-standard, multi-carrier designs that
are field configurable on-the-fly for each individual
application.
The HMC1044LP3E is packaged in a compact
3x3 mm QFN leadless package.
