Coaxial Connectors (RF) provide high-performance connections for a variety of applications in the radio-frequency (RF) spectrum. A key member of this family of connectors is the PA9644 from Amphenol, a connector designed to provide superior performance when connected to low-frequency coaxial cables. This article will discuss the application field and working principle of the PA9644.

The PA9644 connector is designed for use in low-frequency applications such as radio-frequency amplifiers, antennas, and transmitters. It is also used in applications where high power is necessary, such as in medical imaging systems. The low-frequency range of the PA9644 is 7.5 – 65 MHz. The connector has an impedance of 50 ohms, which allows for maximum power transfer while minimizing losses. This type of connector is also designed to be low-profile, which makes installation easier when space is limited.

The PA9644 is a push-on connector with an internal threaded locking mechanism. This connector is available in two sizes – N Type and TNC Type. Both sizes are available with center pins of 6.3mm, 5.0mm, and 4.1mm. The connector also features a soldermask which provides a low-loss connection point. The PA9644 also has a two-part removable insulation sleeve which prevents internal wiring from short-circuiting.

The connector’s working principle is that when the male connector is inserted into the female connector, it activates the internal threaded locking mechanism. This locks the two connectors together and creates a seal which improves signal integrity and RF performance. The metallic components of the connector are also designed to provide highly reliable electrical connections.

The PA9644 is a popular choice for a variety of applications due to its ability to provide a reliable, low-loss connection. It is often used in applications where space or design constraints limit the use of conventional coaxial connectors. With its superior performance, the PA9644 is the ideal choice for any application requiring a reliable, low-loss, and low-profile RF connection.
