RF Amplifiers

The HMC863ALC4TR is a leading GaAs MMIC amplifier module from Analog Devices, Inc. It is a monolithic amplifier module that consists of active and passive components. This amplifier module offers high gain, low noise, and excellent linearity. It is an ideal solution for portable radio, Wi-Fi, and cellular base station applications where low noise, low distortion and high linearity are required.

Application Field

The HMC863ALC4TR amplifier module is suitable for use in a wide range of applications such as GSM, EDGE, WCDMA, LTE, Fixed Wireless Access (FWA), Wi-Fi (WLAN), Multi-mode Handsets, Portables, Condition Monitoring, and test equipment. It is especially suitable for applications that require low noise, low distortion, and high linearity.

Working Principle

The HMC863ALC4TR amplifier module is based on a GaAs pseudomorphic high electron mobility transistor (pHEMT) process. The amplifier module incorporates an active component, a pHEMT device, and a few passive components, e.g. resistors, capacitors, reactances, inductors, and an IP3 limiter. The amplifier module offers high gain, low noise figure, and low distortion. The active component of the amplifier is a pHEMT device that operates in a wide range of frequencies from DC to 4GHz. The pHEMT device provides an amplifier stage with high gain and low noise. It is also able to provide wide dynamic range operation within its frequency range. The amplifier module also includes resistors, capacitors, and other passive components that form a AC or DC feedback network. This network helps the amplifier module achieve high gain, low noise, and low distortion. The peak of the amplifier module’s transfer characteristics curve is typically above the IP3 rating of the amplifier module, providing good linearity performance. The amplifier module also offers an IP3 limiter, which helps prevent the amplifier from being saturated, improving the amplifier’s dynamic range.

Conclusion

The HMC863ALC4TR amplifier module is an ideal solution for systems requiring high gain, low noise, low distortion, and high linearity, such as portable radio, Wi-Fi, and cellular base station applications. It is based on a GaAs pseudo-morphic high electron mobility transistor (pHEMT) process and is capable of operation in a wide frequency range up to 4GHz. The amplifier module also has an IP3 limiter, ensuring high dynamic range operation.
