The HSMP-3890-TR2G is a silicon bipolar Monolithic Microwave Integrated Circuit (MMIC) from Avago Technologies. It is a low-noise amplifier (LNA) designed for applications in broadband wireless systems such as femtocell, mobile WiMAX, LTE, Wi-Fi, and other radios. The HSMP-3890-TR2G has a high gain of 21.5 dB, low noise figure of 0.9 dB, and a high linearity (IIP3 of 38 dBm). The device operates at a frequency range from 3.5 GHz to 4.2 GHz and supports a supply voltage of +5V. It is available in a miniature, surface mount package.

The HSMP-3890-TR2G is a low-noise amplifier (LNA) with a single-stage design, which is ideal for wireless applications that require low noise and high linearity. It is a high yield, high performance MMIC LNA consisting of a high speed JFET input, a pHEMT device, and a nitrogen-implanted GaAs process. It is made with a single-stage, unbalanced design and is generally used for its high gain and low noise figure. Additionally, the high 3rd order IP3 performance makes it suitable for applications requiring stringent linearity.

The HSMP-3890-TR2G is designed for a wide range of applications such as cellular base stations, WiFi hotspots, femtocells, and various high speed wireless communication systems. It is used in these systems to amplify low strength signals and reduce noise. The device features high linearity, high gain, and low noise performance which make it an ideal choice for these applications. It is also designed for high linearity, high gain, and low noise operation even in noise sensitive environments.

To understand how the HSMP-3890-TR2G operates, we must first understand the principles behind its operation. At the heart of its operation lies the device’s ability to amplify signals with minimal noise. The device works by drawing the electrical current from the power supply, amplifying it and then sending it out to its output port. The input is connected to an amplifying transistor known as the active device, which is then connected to the output capacitor. The input and output capacitors act as a tuned circuit, wherein the input capacitor allows signals with a certain frequency to enter the amplifier and the output capacitor allows signals with a certain frequency to be delivered to the output. The active device amplifies the signals and the output is the amplified signal.

The HSMP-3890-TR2G is also designed for maximum efficiency and minimum noise. This is achieved using the device’s interstage matching. Interstage matching is the process of adjusting the amplification, attenuation, and distortion of all the parts involved in the signal path, including the active device, input capacitor, and output capacitor. Interstage matching helps to ensure that the device operates efficiently and without generating unwanted noise.

The HSMP-3890-TR2G is an excellent choice for applications requiring high gain, low noise performance, and stringent linearity. The device can operate with a single stage, unbalanced design, which leads to a high gain and low noise figure. Additionally, the device’s interstage matching ensures maximum efficiency and minimum noise. All of these features make the HSMP-3890-TR2G an ideal choice for high performance LNA solutions for wireless applications.
