The HMC324MS8G is a high efficiency GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC amplifier that contains two un-connected amplifiers in parallel inside an 8 lead MSOPG package. When used in conjunction with an external balun, the outputs of the amplifier can be combined to reduce the 2nd harmonic distortion that is generated by the amplifier. With Vcc at +7.5V, the HMC324MS8G offers 13 dB of gain and with power combining and harmonic cancellation, +22 dBm of output power can be achieved. Using a Darlington feedback pair results in reduced sensitivity to normal process variations and provides a good 50-ohm input/ output port match. This amplifier is ideal for RF systems where high linearity is required. The design can operate in 50-ohm and 75-ohm systems which makes it ideal for CATV head-end and modem, and MCNS applications.
