CLA4601-000

CLA4601-000 is a type of RF diode which is designed to be used in frequency up to 8GHz. It is used in various applications to support various functions, from generating a low-noise local oscillator to a low-cost sub-harmonic mixer. It is important to understand the working principle of the diode and its usage applications to make the most out of it.

Application Field:

The CLA4601-000 diode is most commonly used in wireless applications. It is classified as low-band noise figure broadband transfer switches, low distortion sub-harmonic mixers and low noise amplifier (LNA) applications. It can also be used in radio-frequency (RF) circuit designs, CATV and satellite receiver RF sections. Other potential applications of the CLA4601-000 diode include miniature high-frequency amplifiers, line-of-sight transmitters, monolithic microwave integrated circuits, portables, satellite uplink base stations, shortwave receivers and telecom relay stations.

Working Principle:

In order for an RF diode to working correctly, it must have a very low junction-to-gate capacitance. The CLA4601-000 diode is designed with an integrated field-plate to reduce junction-to-gate capacitance so that the diode works properly. The field-plate also helps to increase the breakdown voltage of the diode, increasing its operational strength and reliability. In addition to the field-plate construction, the CLA4601-000 diode is also designed with an optimized mesa structure. The mesa structure is used to control the thermal characteristics of the diode in order to prevent it from overheating during operation.

Moreover, the CLA4601-000 diode is designed with a gold-plated oxide layer that provides high conductivity and low surface resistance. The oxide layer also helps in reducing the noise generated by the diode during operation. Furthermore, the diode is also designed with thermal-electric cooling, which ensures there is no excessive heat generated during operation, further increasing its operational strength and reliability.

Conclusion:

The CLA4601-000 RF diode is designed for use in applications such as low-band noise figure broadband transfer switches, low distortion sub-harmonic mixers, and low noise amplifiers. Its integrated field-plate design and optimized mesa structure contribute to improved characteristics such as lower junction-to-gate capacitance, increased breakdown voltage, and reduced operating noise. Its gold-plated oxide layer and thermal-electric cooling functioning further improve its working characteristics and reliability.
