4mA to 20mA or fieldbus application data volume surge and volume consistency


B11G3338N80D Push-Pull 3-Stage Fully Integrated Doherty RF Transistor - This transistor is the carrier product of the GEN11 Macro driver family covering all frequency bands below 6GHz. Covering the 3.3 to 3.8GHz frequency range, this high-efficiency multi-band device enables the next generation of high-power and market-leading efficiency macro base stations.


The level of integration of the B11G3338N80D significantly simplifies the design process, reduces BOM cost and ensures reliability and volume consistency.


Small footprint pin-to-pin compatible packages targeting sub-6GHz frequency bands minimize layout effort, which is critical for today's space-constrained applications.


The impeller pump relies on the rotation of the impeller to increase the kinetic energy and pressure energy of the liquid passing through the impeller, and then partially stagnate the kinetic energy of the liquid in the diffuser behind the impeller and convert it into pressure energy. Such pumps include centrifugal pumps, steam core pumps, and screw pumps.


At present, the most commonly used in civil aviation engines are involute spur gear external gear pumps, axial inclined variable displacement piston pumps, rotary plate pumps and centrifugal pumps.


The gear pump is a quantitative pump, the working volume is not adjustable, and there is a one-to-one correspondence between the flow rate and the rotational speed. When the rotation speed is constant, the oil supply is adjusted by the bypass oil return, that is, the oil supply of the gear pump is always higher than the oil demand, and the excess oil is returned to the oil pump inlet.


4mA to 20mA or fieldbus applications also began to encounter bottlenecks due to the proliferation of data volumes, so Ethernet began to become the communication standard.


The standard 4-wire Ethernet solution has evolved into a 2-wire solution, which we call 10BASE-T1L, which consists of a single twisted pair or single-pair Ethernet (SPE). 10BASE-T1L sits on top of the physical layer and is compatible with existing 100Mbps or 1000Mbps industrial Ethernet technology, so it can be used as a complement.


Unlike mechanical engineering or factory automation, the sensors and actuators of process automation are often at a distance from the control system or remote I/O system. Common distances are 200-1000 meters or more.
