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).
Low current consumption: 3.6 mA
Input/output impedance internally matched to 50 Ω
Single DC supply: 1.8 to 2.85 V
Minimal number of external components required
Ultra-small QFN (6-pin, 0.7 x 1.1 mm) package
(MSL1, 260 C per JEDEC J-STD-020)
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.
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 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

Technical Description
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY65605-21 are provided
in Table 2. The recommended operating conditions are specified
in Table 3 and electrical specifications are provided in Tables 4
and 5.
Power Shutdown
The VEN signal (pin 6) enables or disables the LNA DC power. A
logic high signal powers on the LNA and a logic low signal powers
off the device.

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.
