L2720W13TR Application Field and Working Principle

The L2720W13TR, or LingJie Wideband Transceiver, is a revolutionary new device in the field of linear amplifiers, instrumentation, and OP amps. This device can be used in a wide range of applications, such as integrated radio systems, audio equipment, and automotive systems. It is well-suited for applications requiring high frequency, wideband performance.

Application Field

The L2720W13TR is a compact, wideband transceiver that combines the functionality of a broadband amplifier and a front-end tuner. The wideband transceiver is based on a zero-IF architecture, and it is designed for use in applications such as military communications and vehicular radars. The transceiver can accommodate up to eight frequency bands with a single device, and its 270±MHz bandwidth covers a wide range of applications.

The L2720W13TR also has low power consumption, making it ideal for battery-operated applications such as portable communication equipment. It also has high linearity, which makes it an ideal choice for systems that require precise signal amplification with minimal distortion.

Working Principle

The L2720W13TR is based on a zero-IF architecture, which is essentially a circuit configuration that includes two mixers and a loop filter. The incoming signal is first mixed by a down-converting mixer and then converted to the baseband signal, which is then filtered by the loop filter. Finally, the signal is up-converted by an up-converting mixer, producing the output signal.

The L2720W13TR is equipped with adaptive gain control, which helps maintain uniform gain across the entire frequency range. This capability allows the device to compensate for the differences in signal strength across various bands, making it possible to maintain a constant performance even when the circumstances change. Additionally, the L2720W13TR has an integrated voltage-controlled oscillator, allowing for precise frequency control and flexibility.

The L2720W13TR also uses a six-mode amplifier to deliver high-power output. The amplifier is composed of three power stages, which can produce up to 160W of output power. The amplifier also has a linearity of over 65dB and high gain and low noise figure, making it suitable for applications that require high-fidelity performance.

Conclusion

The L2720W13TR is a powerful and versatile device that can be used in a wide range of applications. Its wideband operation, high linearity, and low power consumption make it an ideal choice for battery-operated applications. Additionally, the device’s integrated voltage-controlled oscillator and high-power amplifier provide for precise frequency control and high-fidelity operation. This makes the L2720W13TR an excellent choice for applications requiring reliable and precise performance.
