Описание товара

TQP9111 is a highly integrated, high-performance RF amplifier that uses advanced semiconductor technology and surface mount packaging, with a compact structure and excellent electrical performance. The amplifier is suitable for wireless communication bands from 1.8 GHz to 2.7 GHz and is widely used in wireless infrastructure such as repeaters, boosters, distributed antenna systems (DAS), pico base stations and macro base stations.

Функции
1. High frequency range and gain:
Operating frequency: 1.8 GHz to 2.7 GHz, covering multiple wireless communication bands.
Gain: The typical value is 29.8 dB, which effectively enhances signal strength and improves communication quality.
2. Excellent linearity and output power
—Output third-order intercept point (OIP3): +46 dBm, ensuring good linearity at high power output and reducing signal distortion.
—1 dB compression point (P1dB): +32.5 dBm, meeting high-power amplification requirements and improving communication distance and coverage.
—Low noise figure (NF): 6.2 dB, effectively reducing noise interference during signal transmission and improving the sensitivity of signal reception.
3. Flexible power management
—Adjustable bias: Both the input and output stage amplifiers support bias adjustment, which can adjust the power consumption according to the actual application requirements to achieve energy saving.
—Shutdown function: The amplifier can be turned off when not in use or in specific application scenarios such as TDD (time division duplex) systems to further reduce power consumption.
4. Optimized inter-stage matching: The integrated inter-stage matching network reduces performance changes caused by external matching component values and placement tolerances, and improves system stability and reliability.
5. Externally adjustable output matching: The output matching network can be externally adjusted to facilitate the optimization of the amplifier’s performance in high-power or high-linearity applications to meet the needs of different application scenarios.
