HMC594-SX

The HMC594-SX is a MMIC-based medium power, high third-order intercept/input P1dB-out and gain/noise figure RF amplifier. It operates from 2-8 GHz and is well-suited for a variety of automated test equipment applications such as communications, spectrum analysis, and signal intelligence. The amplifier is internally matched to 50-Ohm for single-ended use. The amplifier has a minimum supply voltage of +3.3V with draws only 23mA of current and provides up to 12.5 dB gain and 14 dBm of output power. The amplifier boasts a high third-order intercept point of 28dBm with a maximum noise figure of 3.5 dB. The working principle of the HMC594-SX operates according to a model of Radio Frequency (RF) amplification. This model uses both an input gain stage and an output gain stage; the two stages independently amplifying the signal to provide the necessary gain and power output. The input stage consists of a number of active devices, such as bipolar transistors, MOSFETs, or JFETs. The devices are biased so that they will draw current and provide the necessary amplification. The output stage contains the same active devices and is operated in a similar fashion, but in this case the devices are used to further amplify the signal to achieve the desired output power.The major application field for this amplifier is automated test equipment, where it offers improved linearity, higher output power while using small-sized and low-cost circuit elements. The amplifier is also well-suited for array bandwidth expansions, high dynamic range amplifiers, and aperture filling, as it has consistently good dynamic range, linearity, and output power. It can be used as a pre-driver in transmitters and as intermediate power amplifiers in receivers. In addition, it can be used as an intermediate power amplifier in wireless infrastructure applications, as well as in low-power, compact and low-noise RF systems.In summary, the HMC594-SX is an ideal high linearity, low-noise medium power RF amplifier for automated test equipment and wireless infrastructure applications. It offers low current consumption and good gain and noise figure performance, while being cost-effective and available in a small-sized package. With a wide frequency range of 2-8 GHz, the amplifier can be used as a pre-driver in transmitters, as an intermediate power amplifier in receivers, and as an intermediate power amplifier in wireless infrastructure applications.
