Description

The SKY65623-682LF is a Microwave Monolithic Integrated

Circuit (MMIC) front-end low-noise amplifier (LNA) designed for

Global Navigation Satellite System (GNSS) radio receiver

applications. The device provides low current consumption,

excellent gain, and a superior noise figure (NF). Output matching

components are embedded inside the device. Only one external

input matching inductor is required.

 Minimal number of external components required

 Small QFN (5-pin, 0.8 × 0.8 mm) package

(MSL1, 260 C per JEDEC J-STD-020)

The SKY65623-682LF is optimized to operate at 1559 to

1606 MHz, which makes it ideal for

GPS/GLONASS/Galileo/Compass radio receiver applications.

Skyworks Green^TMproducts are compliant with

all applicable legislation and are halogen-free.

For additional information, refer to Skyworks

Deﬁnition of Green^TM, document number

SQ04–0074.

The SKY65623-682LF is fabricated using advanced SiGe BiCMOS

technology. The LNA uses surface-mount technology (SMT) in the

form of a 0.8 × 0.8 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.
