RF amplifiers are electronic amplifiers that operate within the radio frequency range. RF amplifiers are highly useful in many commercial and industrial applications. The RF5187TR7 is a type of RF amplifier that is gaining more attention in the market due to its great performance and cost-effectiveness. It is a two-stage amplifier designed for broadband applications with low power consumption. In this article, we will discuss the application field and working principle of the RF5187TR7.

The RF5187TR7 is best suited for radio frequency applications operating in the 800 MHz – 2.5 GHz range, such as digital TV broadcasting, cellular networks, and wireless LANs. It can also be used in digital satellite systems, distributed antenna systems, and other digital RF applications. The RF5187TR7 is ideal for the medium-power applications due to its low noise figure, high linearity, and high efficiency. It is also suitable for high-level mixing and pre-amplification required for wide-area radio links.

The RF5187TR7 is a two-stage amplifier with a single-ended input and a single-ended output. It is based on a tightly coupled double balanced structure with two complimentary push-pull stages and has an overall gain of approximately 22.5 dB. The RF5187TR7 employs a wideband matching network composed of a series capacitor, an inductor, and a shunt resistor. This network is used to match the amplifier’s broad frequency range.

The RF5187TR7 also has an on-chip impedance matching network. It performs two important functions, providing broadband AC input and output matching, and providing high linearity over temperature. The matching network consists of two inductors, two capacitors, and two varactors. It is capable of providing excellent harmonic distortion and noise performance over temperature and frequency.

The RF5187TR7 works by amplifying the input signal, increasing its power and making it stronger, and also improving its fidelity. It provides an optimal noise figure of 5 dB with high P1dB output power up to 10 dBm per stage. The amplifier also features high linearity with a third order intercept point (IP3) up to 45 dBm and a fourth order intercept point (IP4) up to 55 dBm without external components.

To sum it up, the RF5187TR7 is an excellent choice for applications operating in the 800 MHz – 2.5 GHz range. It is a two-stage amplifier that is designed for broadband applications with low power consumption, and has an overall gain of approximately 22.5 dB. It features a tightly coupled double balanced structure with two complimentary push-pull stages, an on-chip impedance matching network, and provides an optimal noise figure of 5 dB with high P1dB output power up to 10 dBm per stage.
