Description
The SKY65605-21 is a Microwave Monolithic Integrated Circuit
(MMIC) front-end low-noise amplifier (LNA) designed for BeiDou
Satellite Navigation System/Global Positioning System/Global
Navigation Satellite System (BDS/GPS/GNSS) receiver
applications. The device provides high linearity, excellent gain, a
high 1 dB input compression point (IP1dB), and a superior noise
figure (NF).
The SKY65605-21 is optimized to operate from 1.559 to
1.606 GHz, which makes it ideal for BDS/GPS/GNSS radio
receiver applications.
The SKY65605-21 is fabricated using advanced SiGe BiCMOS
technology. The LNA uses surface-mount technology (SMT) in the
form of a 0.7 x 1.1 mm Quad Flat No-Lead (QFN) 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
Table 1.
