The HMC375LP3E is a high-performance Class AB medium-power amplifier, utilized in a wide variety of radio frequency (RF) applications. It is a wideband differential amplifier featuring wide bandwidths with an input frequency range from DC to 6 GHz. With its wide dynamic range, excellent gain flatness, and high output IP3, the HMC375LP3E can be utilized for any type of general-purpose RF application.

The HMC375LP3E is a monolithic device, which incorporates an at-speed, low noise amplifier, a differential-to-single-ended amplifier, and a gain setting circuit into a single package. Its efficiency has been enhanced through the use of a MOSFET input port, allowing for a high gain output with very low current consumption. The amplifier operates on a single +5V supply and draws very little current, thus making it ideal for mobile and battery-operated systems.

The HMC375LP3E is used in a variety of RF applications such as cellular/PCS base station amplifiers, wireless LANs, wideband communications receivers, and satellite communications. It can be used for short- and long-distance communication systems, as well as for high-speed data transmission. Additionally, the HMC375LP3E is ideal for both point-and multipoint systems, due to its wide dynamic range and low power consumption. The amplifier also offers outstanding linearity and harmonic rejection, enabling its use in applications such as high-power point-to-point radio links.

The HMC375LP3E is designed to provide high gain, excellent linearity, and high power output with low noise figures. It achieves this performance using its high-input and low-output impedances, along with an input stage featuring MOSFET and LDMOS devices. The amplifier is capable of driving up to 33 dBm of output power at 6 GHz, and it can achieve a maximum gain of 20 dB. It also features a wide dynamic range, allowing it to perform in robust RF environments.

The working principle of the HMC375LP3E is based on the combination of differential and single-ended amplification. The amplifier takes two inputs—one differential and one single-ended, and produces an amplified single-ended output. The amplifier operates on a low-voltage single-supply (5V), enabling low-power operation while still providing high gain and excellent linearity. The HMC375LP3E also features a gain setting circuit that allows users to adjust the amplifier’s gain from 0 to 20 dB.

In summary, the HMC375LP3E is a versatile, high-performance medium-power amplifier that is ideal for a variety of RF applications. It features a wide frequency range, low-voltage single-supply operation, high gain, excellent linearity, and high power output with low noise figures. This makes it an excellent choice for wireless LANs, cellular/PCS base station amplifiers, wideband communications receivers, and satellite communications. Additionally, the amplifier’s gain setting circuit allows users to easily adjust the amplifier’s gain from 0 to 20 dB.
