Definition of GreenTM, document number
SQ04-0074. Description
The SKY65725-11 is a shielded front-end module (FEM) with an
integrated low noise amplifier (LNA) and pre-filter designed for
Global Positioning System / Global Navigation Satellite System /
Beidou Navigation Satellite System (GPS / GNSS / BDS) receiver
applications. The device provides high linearity, excellent gain, a
high 1 dB input compression point (IP1dB), and a superior noise
figure (NF).
The pre-filter provides the low in-band insertion loss and
excellent rejections of the cellular, PCS, and WLAN frequency
bands. The SKY65725-11 uses surface-mount technology (SMT)
in a Multi-Chip Module (MCM) package, which allows for a highly
manufacturable and low-cost solution.
An additional filter is incorporated in the SKY65725-11 to improve …
