Description

HJ-12002 is Two-Way Power Divider. A two-way power divider, also known as a two-way splitter or power combiner, is an electronic device used in RF (radio frequency) and microwave systems to divide an incoming signal into two equal or nearly equal output signals with a specified phase relationship. These devices are commonly used in various applications, including telecommunications, radar systems, and wireless communication systems.

Guaranteed Specifications (-54° to +85°C)

1. Frequency Range 0.01 to 10 MHz

2. Isolation 30 dB Min.

3. Insertion Loss 0.5 dB Max.

4. VSWR 1.3:1 Max.

5. Phase Balance ±1° Max.

6. Amplitude Balance ± 0.1 dB Max.

7. Impedance 50 Ohms

8. Power Handling 3 Watts Max.

Two-way power dividers are part of a broader category of power dividers and combiners, which includes devices that split signals into more than two outputs or combine signals from multiple inputs into one output. These devices play a critical role in maintaining signal integrity and phase relationships in various RF and microwave applications.

Description

The MA8920 is 900V, 5A, Switching Power Supply IC. Switching power supply ICs are used to efficiently convert electrical power from one voltage level to another using high-frequency switching techniques. They incorporate control circuitry to regulate the output voltage or current based on feedback and control signals.

Switching power supply ICs with a 900V, 5A rating are typically employed in applications such as industrial power supplies, motor drives, solar inverters, electric vehicle charging stations, and other high-power applications where high voltage and moderate current levels are required.

The MA8000 series is a power supply IC module that contributes to energy saving during standby. This product incorporates a control circuit and a main switch element, and can configure a partial resonance RCC converter with a small number of external components. High efficiency, low noise standby low power consumption can be realized by the conventional power supply design method.

Features:

1. Power consumption is very low at micro loads. (Load power 50mW, input voltage AC 100V, input power 0.5W or less.)

2. High efficiency over a wide range of loads. (Efficiency 80% or more at rated load.)

3. Feedback noise is very small. (Vcci-class B compliant.)

4. The oscillation operation is stable even with a minute load.

5. With soft start function.

6. The number of electrical parts is small and the circuit configuration is simple.

7. As IC modules can be selected according to the input / output specifications, design method can be unified and design time can be shortened.

8. Adoption of a full mold package is advantageous for insulation design.

9. All-round input design is also possible.    […]
