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 1.5500 to

1.6018 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.
