The SKY55951-11 front-end module (FEM) features an integrated
L1 low-noise amplifier (LNA) and post-filter along with an L5 LNA
and post-filter designed for Global Navigation Satellite System
(GNSS) receiver applications.
Part of our Sky5® portfolio, the SKY55951-11 provides high gain,
low current consumption, and integrated input and output
matching for both L1 and L5, all in a compact 2.0 x 1.6 mm
The L1 path also features an integrated B13 notch filter, providing
excellent suppression (-50 dBm) of cellular low-band 2nd
harmonic signals impacting GPS L1 reception. The post-filtering
on the L5 path also provides high (> 45 dBc) out-of-band
rejection for interference below 1 GHz.
The SKY55951-11 uses surface-mount technology (SMT) in a
Multi-Chip Module (MCM), a proven and highly manufacturable
