The APTC80H15T3G is an integrated circuit (IC) belonging to the family of arrays of field-effect transistors (FETs). This IC is designed for wide-band switches and low-noise signal processing applications in mobile handsets and other digital communication systems. This post will explain the application field of the APTC80H15T3G, as well as its working principle.

The APTC80H15T3G is a reliable, low-cost solution for wide-band applications, such as cellular networks, PCS, W-CDMA and 3G. In addition to its practicality in terms of cost, the APTC80H15T3G also provides a number of technical advantages, such as high gain, low insertion loss, low VSWR, low output power, and wide operating temperature range. It is well suited for linear-in-phase signal processing applications, and can be used as an efficient replacement for more complex, larger switch designs.

The device\'s integrated circuits incorporate 15 transmission channels, each of which comprises a pair of normally closed FETs: the drain FET, which controls the input signal, and the reference FET, which controls the output signal. The FETs are configured in a monolithic array and share a common gate. This configuration ensures that the performance of each FET remains consistent across all channels, even if the surrounding environmental conditions change.

The APTC80H15T3G implements a unique control scheme that allows it to switch between active and inactive states on a single line. This scheme is implemented by using a current source to generate a regulated current, which is then applied to the gate of each FET in the array. When this regulated current is applied, the FET is active, allowing a signal to be transmitted. When the regulated current is removed, the FET is switched off and the line is inactive. This process is repeated for each of the FETs in the array.

In addition to its ability to switch quickly between active and inactive states, the APTC80H15T3G also features a number of other practical advantages. It has low source impedance, low noise generation, and a high signal-to-noise ratio. It is also resistant to surge currents and ESD, making it a reliable choice for digital communications applications. In addition, the APTC80H15T3G is reverse-polarity protected and short-circuit proof, adding further to its robustness and reliability.

In summary, the APTC80H15T3G is a suitable choice for wide-band applications due to its cost-effectiveness and technical advantages. Its integrated FETs, configured in a monolithic array, can be used for linear-in-phase signal processing applications, and the device can be switched quickly between active and inactive states using a current control scheme. The APTC80H15T3G is also robust and reliable, with low source impedance, low noise generation, and a high signal-to-noise ratio.
