Functional Description
The SKY65047-360LF is a single stage, low noise amplifier in a
low-cost
surface mount package. The device operates with a
single +3.3 V power supply connected through an RF choke to the
output pin. Surface mount capacitors provide DC bias decoupling
for VCC.
The bias current is set by a reference voltage transistor and by
resistor R1. Pin 2 (RF_IN) is the RF input and Pin 7 (RF-OUT/BIAS)
is the RF output. The part is externally RF matched and DC
blocked using surface mount components to facilitate operation
over a frequency range of 0.4 to 3.0 GHz. Pins 1, 3, and 4, and the
package backside metal provide the DC and RF ground.

Note:
The SKY65047-360LF includes an internal PA enable (pin 8, EN)
for fast RF on/off control. A logic low voltage level disables the PA;
a logic high voltage level enables the PA.

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.
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.
EtherCAT（Ethernet for Control Automation Technology）是一种基于以太网的开发构架的实时工业现场总线通讯协议，EtherCAT是最快的工业以太网技术之一，同时它提供纳秒级精确同步。相对于设置了相同循环时间的其他总线系统，EtherCAT系统结构通常能减少25%-30%的CPU负载，EtherCAT的出现为系统的实时性能和拓扑的灵活性树立了新的标准。...[详细]
