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 GreenTM products are compliant with
all applicable legislation and are halogen-free.
For additional information, refer to Skyworks
Definition of GreenTM, 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.
