The HMC491LP3E is a low noise, wide gain control range, GaAs PHEMT high power amplifier designed for use in the L-Band. It is ideally suited for Point-to-Point Microwave, Point-to-MultiPoint, Test Instrumentation, and VSAT applications.
The HMC491LP3E is housed in a compact 8-lead plastic package and operates from +5.0V (typical) supply voltage. The amplifier offers +25dBm (typical) power gain, 1.8:1 VSWR, and +27dBm (typical) power output. The amplifier also features a wide gain control range of 0 to 30dB at 6.5GHz and a low noise figure of 0.8 dB at 6.5GHz.
The HMC491LP3E is ideally suited for a wide range of high power amplifier applications requiring a low noise figure, wide gain control range, and exceptional linearity in the L-Band. It is designed to meet the high performance requirements of high power amplifiers, such as Point-to-Point Microwave, Point-to-MultiPoint, Test Instrumentation, and VSAT applications.
The working principle of the HMC491LP3E is based on the use of a GaAs PHEMT as the transducer, which is connected to an active bias system. The active bias system is connected to the supply voltage and consists of an amplifier, whose gain is set by a wide-range, low distortion, low noise feedback network. This amplifier serves to adjust the current flowing through the PHEMT
As a result, the gain of the amplifier can be set over a wide range. The output power of the amplifier is then determined by the control voltage. This active bias system allows the amplifier to be used for many different applications with different requirements for gain, noise, linearity, and power. Additionally, the active bias system helps to stabilize the gain of the amplifier over temperature and supply variations.
The HMC491LP3E is a high-performance amplifier that is suited for a wide range of applications in the RF and wireless communication systems. It offers wide gain control range, low noise figure, and exceptional linearity, and is designed to meet the demanding requirements of high power amplifier applications.
