HMC188MS8TR is a range of RF Misc ICs and Modules from Analogue Devices Inc, a world-leading provider of high performance background in semiconductor solutions. The range is designed to function as low noise amplifiers (LNAs) in both receive and transmit paths. The HMC188MS8TR series is ideal for multi-mode and multi-band systems in wireless applications, such as cellular, WiFi, and consumer electronics.

The RF Misc ICs and Modules series offer the industry’s highest linearity for very high dynamic range applications. In addition to the high supply voltage operation, the HMC188MS8TR can be used in industrial, medical, automotive, and other applications. Lower noise figure, higher linearity, and superior return loss of the series meet the unique requirements of both commercial and industrial applications.

The HMC188MS8TR is a two stage low noise amplifier (LNA) consisting of input matching network, a high-gain, low noise amplifier, and an output matching network. The input matching network helps to prevent unwanted signal reflections from entering the amplifier, while the output network ensures that the amplified signal is focused into the desired load. The input matching network also enables a low noise figure, controlled input impedance, and high isolation among all ports of the amplifier.

The core of the amplifier is the first stage, which is usually a low-noise (LN) field effect transistor. The output of the transistor is connected to the input of the output matching network, which is used to match the impedance between the first stage and the load. The output matching network helps to minimize spillover losses, provides good return losses, and ensures the proper distribution of power between the load and the amplifier. The choice of components for the output matching network depends on the specific application and the desired performance.

The second stage of the HMC188MS8TR amplifier is an open collector amplifier, which is usually used for driving RF components such as antenna switches and oscillators. The open collector amplifier helps to isolate the output from the amplifier so that any noise generated by the amplifier does not affect the components it is driving. The amplifier also features high linearity, low noise, and wide dynamic range, making it ideal for applications such as digital cellular baseline, WiMAX systems, and PCS base stations.

In addition to the above features, the HMC188MS8TR also has a wide operating temperature range of -40°C to +85°C, making it suitable for a variety of environmental conditions. The device is also RoHS compliant, which means that it has been designed to perform efficiently and safely in those conditions. The HMC188MS8TR is available in a wide range of packages, making it suitable for different applications.

The HMC188MS8TR is typically used in applications such as multi-mode and multi-band 900 MHz and 2.4 GHz systems, OFDM, WiMAX, WiFi, MIMO, and any applications that require a low-noise LNA for signal amplification. In addition, the amplifier is also used in applications such as machine-to-machine (M2M) communications, mobile handset measurements and loop challenges, digital cellular base stations, and PCS base stations. The HMC188MS8TR is an ideal solution for high dynamic range applications due to its high linearity and low noise.
