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).

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.

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.

Technical Description

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.

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.

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.
