Description

The SKY65723-81 is a 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

integrated notch filtering for excellent rejections of the cellular,

PCS, and WLAN frequency bands. The SKY65723-81 uses

surface-mount technology (SMT) in the form of a 1.7 x 2.3 mm

Multi-Chip Module (MCM) package, which allows for a highly

manufacturable and low-cost solution.

A functional block diagram is shown in Figure 1. The pin

configuration and package are shown in Figure 2. Signal pin

assignments and functional pin descriptions are provided in
