RF front end (LNA + PA) refers to the system which is composed of an amplifier, a low-noise filter and a power amplifier between a radio frequency (RF) signal source and an RF signal detector. It is commonly used in a diversity of digital communication systems, such as wireless networks, mobile communication systems, and satellite communication systems.

T7024-TRQY is a tiny and power efficient active antenna switch from TriQuint. It integrates low noise amplifier, power amplifier and switch in a single chip, providing a optimal RF front end solution for mobile devices. Due to its small size, low consumption, high power efficiency, and cost saving, T7024-TRQY has been widely used in a variety of mobile applications.

T7024-TRQY is a single channel active antenna switch which comprises of low noise amplifier (LNA), power amplifier (PA) and switch. It helps to match the input impedance of the antenna to the receiver and reduce the noise figure of the receiver. The switch also helps to reduce the power consumption of the receiver when the antenna is not being used. The gain of the LNA in T7024-TRQY is adjustable, and its maximum gain is up to 28.5dB. The power amplifier provides a transmission gain of up to 16dB. The switching time of the switch is less than 10us, which makes it suitable for broadband applications.

In addition, T7024-TRQY also offers a variety of features, such as integrated active balancing, low output noise, high linearity, good reverse isolation etc. These features make it suitable for applications, such as WIFI, 4G, LTE, Bluetooth, RFID and so on. It can be used in both receive and transmit mode for mobile applications.

The working principle of T7024-TRQY is very simple. In receive mode, the input RF signal is passed through the LNA first. Then, the amplified RF signal can be switched via the switch, and then passed through the PA to increase its power. In transmit mode, the input RF signal is amplified by the PA and then passes to the antenna by the switch. This helps to increase the transmission power and reduce the noise of the transmitted signal.

In summary, T7024-TRQY is a tiny and power efficient single channel active antenna switch which can be used in a variety of applications for transmitting and receiving RF signals. Its features can provide good noise figure, high linearity, low output noise, good reverse isolation, and active balancing. In addition, its low consumption, high power efficiency, and cost saving are its major advantages.
