Description
The SKY65088 is a Microwave Monolithic Integrated Circuit
(MMIC) Global Positioning System (GPS) Low Noise Amplifier
(LNA). The device has superior Noise Figure (NF), excellent gain,
and a high 1 dB Input Compression Point (IP1dB).
The SKY65088 is optimized to operate at 1.575 GHz, which
makes it ideal for GPS radio receiver applications.
The device is fabricated using Skyworks high reliability SiGe
CMOS technology. The LNA uses Surface Mount Technology
(SMT) in the form of a 1.5 x 2.0 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.
