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).
 Ultra-small QFN (6-pin, 0.7 x 1.1 mm) package
(MSL1, 260 C per JEDEC J-STD-020)
Skyworks GreenTM products are compliant with
all applicable legislation and are halogen-free.

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.

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.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

Evaluation Board Description
Package and Handling Information
The SKY65605-21 Evaluation Board is used to test the
performance of the SKY65605-21 LNA. Figure 3 shows the
Evaluation Board schematic, and Table 6 lists the Bill of Materials
(BOM) for the SKY65605-21. Figure 4 shows the Evaluation Board
assembly drawing.
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
Package Dimensions
The SKY65605-21 is rated to Moisture Sensitivity Level 1 (MSL1)
at 260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Typical part markings are shown in Figure 5. Package dimensions
for the SKY65605-21 are shown in Figure 6, and tape and reel
dimensions are provided in Figure 7.
