General Description

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.
